| Usage |
Experimental equipment required for the experiment: 1. Microplate reader (450nm) 2. High-precision pipette and gun tips: 0.5-10uL, 5-50uL, 20-200uL, 200-1000uL 3. 37℃ constant temperature box 4. Distilled water or deionized water Sample processing and requirements: 1. Serum: Place the whole blood sample collected in the serum separation tube at room temperature for 2 hours or at 4℃ overnight, then centrifuge at 1000×g for 20 minutes, and take the supernatant, or store the supernatant at -20℃ or -80℃, but avoid repeated freezing and thawing. 2. Plasma: Collect the specimen using EDTA or heparin as an anticoagulant. Centrifuge the specimen at 1000 × g for 15 minutes at 2-8°C within 30 minutes of collection. The supernatant can be assayed or stored at -20°C or -80°C, but avoid repeated freezing and thawing. 3. Tissue homogenization: Rinse the tissue with pre-chilled PBS (0.01M, pH 7.4) to remove residual blood (lysed red blood cells in the homogenate will affect the measurement results). Weigh the tissue and mince it. Add the minced tissue to the appropriate volume of PBS (generally a 1:9 weight-to-volume ratio, e.g., 1 g of tissue sample to 9 mL of PBS. The specific volume can be adjusted according to experimental needs and recorded. It is recommended to add protease inhibitors to the PBS) in a glass homogenizer and grind thoroughly on ice. To further lyse tissue cells, the homogenate can be sonicated or repeatedly frozen and thawed. Finally, centrifuge the homogenate at 5000 × g for 5-10 minutes, and the supernatant can be assayed. 4. Other biological fluids: Centrifuge at 1000xg for 20 minutes, remove the supernatant, and test. Pre-test preparation: 1. Remove the test kit from the refrigerator 10 minutes in advance and equilibrate to room temperature. 2. Preparation of standard gradient working solution: Add 1mL of universal diluent to the lyophilized standard, let it stand for 15 minutes to completely dissolve, then gently mix (concentration is 2000pg/mL). Then dilute to the following concentrations: 2000pg/mL, 1000pg/mL, 500pg/mL, 250pg/mL, 125pg/mL, 62.5pg/mL, 31.25pg/mL, and 0pg/mL. Serial dilution method: Take seven EP tubes and add 500uL of universal diluent to each tube. Pipette 500uL of the 2000pg/mL standard working solution into the first EP tube and mix thoroughly to make a 1000pg/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube is used as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details. 3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately. 4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately. 5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing). Procedure: 1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C. 2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.) 3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes. 4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used). 5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes. 6. Washing: Discard the liquid and wash the plate five times as in step 4. 7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes. 8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm. Calculating experimental results: 1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis. 2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor. |

| Theory | This kit uses a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotin-labeled detection antibody, and HRP conjugate are sequentially added to microwells pre-coated with a capture antibody against Von Willebrand Factor Cleaving Protease (ADAMTS13). After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by peroxidase (HRP) catalysis and to yellow by acid. The intensity of the color is positively correlated with the amount of Von Willebrand Factor Cleaving Protease (ADAMTS13) in the sample. The absorbance (OD) is measured at 450 nm using a microplate reader to calculate the sample concentration. | |||||||||||||||||||||||||||||||||

| Composition |
|
|||||||||||||||||||||||||||||||||
| Background | Von Willebrand factor-cleaving protease (ADAMTS13), also known as ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13), is a zinc-containing metalloproteinase that cleaves von Willebrand factor (vWf), a large protein involved in blood coagulation. It is secreted into the blood and degrades large vWf multimers, reducing their activity. The ADAMTS13 gene maps to chromosome 9 (9q34). Genomically, ADAMTS13 shares many features with the 19 members of the ADAMTS family, all of which have a protease domain (the part that performs proteolysis), an adjacent proteolytic domain, and one or more thrombin domains. ADAMTS13 actually has eight thrombospondin domains. It lacks a hydrophobic transmembrane domain, and therefore is not anchored to the cell membrane. | |||||||||||||||||||||||||||||||||
| General Notes | 1. Strictly adhere to the specified incubation time and temperature to ensure accurate results. All reagents must be at room temperature (20-25°C) before use. Refrigerate reagents immediately after use. 2. Improper plate washing may result in inaccurate results. Ensure that all liquid in the wells is aspirated thoroughly before adding substrate. Do not allow the wells to dry out during incubation. 3. Remove any residual liquid and fingerprints from the bottom of the plate, as this will affect the OD value. 4. The substrate developer solution should be colorless or very light in color. Do not use substrate solution that has turned blue. 5. Avoid cross-contamination of reagents and specimens to prevent erroneous results. 6. Avoid direct exposure to strong light during storage and incubation. 7. Do not expose any reagents to bleaching solvents or the strong fumes emitted by bleaching solvents. Any bleaching agent will destroy the biological activity of the reagents in the kit. 8. Do not use expired products, and do not mix components with different product numbers and batches. 9. Recombinant proteins from sources other than the kit may not be compatible with the antibodies in this kit and will not be recognized. 10. If there is a possibility of disease transmission, all samples should be managed properly and samples and testing devices should be handled according to prescribed procedures. |

Top Book of 2024
Format: Kindle
May Contain Spoilers!
Where do I even begin?
I'm still in shock of how amazing this book was, how it touched my heart, and now how I have to wait for H. M. Wolfe to write the second. Because those last few chapters...went from 0 to 100 quick. So much new information, new relationships and loss, that now the tides have turned, and we NEED more.
This is a fantasy book of love, loss, the power of friendship, and finding one owns strength. TBOC is about Hyacinth whose home is at Asrai’s Academy for Orphans. She was torn between the safety of home or leaving it all behind for a chance at a new life. But when a mysterious messenger appears, whispering rumors of a God among Fae, everything Hyacinth thought she knew about the Realms comes crashing down, and she must now make a new journey.
This book ate me up and spit me back out. I was not anticipating the emotions I would feel within these pages. I'm talking I was laughing, then I was swooning, then I was on the edge of my seat, then I'm ready to slap someone, then I'm rooting so hard for certain characters I don't wan to stop, then my heart is broken, then I'm excited af.... it was all an emotional rollercoaster. The last few chapters contained a lot of new information, so of course as much as it doesn't leave off on a complete cliffhanger, I was over here like scraping the bottom of an ice cream cup, wanting more.
The magic system starts out ambiguous, but as you continue reading you start to get more and more to build off of and start to piece together the world H. M. Wolfe created. TBOC brings in eight main characters that test alliances, grow in friendships, fall in love, become a team, and even break bonds.
The friendship among the girls was everything. Ata is a spit fire, Pria is sweet yet terrifying. The banter and protectiveness these three had for one another made me want to join in with them for breakfast. I liked how there was multiple romances going on at once. Yes we have the main characters, but it just wasn't always about them, and it was great to see how others shifted and grew too.
And last the romance, I've never rooted so hard for two characters. We're talking slow burn between them. In the beginning you're not sure how this is all going to play out, but Landers is a tatted, "touch her and die" kind of MMC, which who cannot love that? Hyacinth definitely had to grow within the chapters and learn how to be strong, because sometimes she was making me mad and I just wanted to step in there for her. But Landers was everything she needed and it was so well written, which is why by time you get to the end you only want more of them!

cliffhanger, no 2nd book in sight
Format: Kindle
The book itself was pretty good. The plot is unique and full of suspense and action, although some of it felt redundant. I particularly enjoyed the realistic growth cycle of the female lead from abuse survivor with low self-esteem to badass warrior.
I never would have read it though if I had known this is not complete, and there is no information available on the next book.

The Book of Cin relies heavily on the progression and growth of our fmc, which I don't hate. It shows us the girl she was and what she allowed and who she then grows into by the end due to all the events that happens within the book. This journey - physically, mentally, and especially emotionally - takes us through her current and past experiences and expresses how one can grow from trauma. Her support group is invaluable, and the new relationships she forms prove to be just as prominent to her and her growth. This is truly a story that thrives on the characters growth throughout the book and sets us up in how to see her for the coming books.
My half star comes from the pacing. Though I *thoroughly* enjoyed the ending and seeing this growth take full effect, I believe that it came with just too many pages. Sitting at about 500, we get intimate and detailed scenes that we could have maybe gone without. Oftentimes, I found myself daydreaming away from the book until something more prominent peaked my interest again. I understand the depth the book goes into to fully establish this character development and the setup that this provides for the rest of the series, but I truly do believe there were scenes that could have been cut out to help with the pacing.
If you're not into slow pacing (and usually I'm not), this book is still worth the read. The ending more than makes up for it, and it is absolutely detrimental to the story that we get the events that occur and see the development take shape in front of our eyes. It makes you fist pump the sky by the end.

This was one of those books I have a hard time reviewing because I struggle to find the words to adequately express how incredible it was! This book deserves every single star! It is heart-wrenching, emotional, and heavy. The depictions of self-worth, guilt, loss, love, and everything in between were done beautifully. There are multiple romances to root for and the development of the plot/world was executed brilliantly. It has an amazing set of characters that will bring out not only all the rage/hate but also sacrifice that will impact your soul! The ending of chapter 19 will live rent free in my mind and is now one of my top favorite moments from any book and why Landers will forever take a top spot in my all-time favorite book boyfriends! The depiction of what true friendship should be is also well represented! Ardan stole my heart as the best side character and if you’ve read this we need to talk (iykyk)!! I absolutely need the next book to see what happens next!!

Epic Adventure with FMC coming into her power
Format: Kindle
Honestly, the author, HM Wolfe had me at the dedication:
“For my readers. For the ones who suffer silently. You will not break.”
About: The Book of Cin takes us on a heart wrenching and inspiring journey of love, betrayal, self discovery and healing where everything Hyacinth thought she knew about the realms - and herself - is turned upside down. As she learns about her own dormant magic, she must also find her courage and make sacrifices to protect her friends as the threat of war hangs over them.
My reactions: Holy smokes, this was amazing! First off, I have to say that the trauma Hyacinth experiences from the emotional and physical abuse of her narcissistic boyfriend hit hard for me. It was written so realistically, and I especially appreciate the author’s accurate betrayal of what this type of trauma does to one's self-esteem and character. Her healing journey and growth throughout the story is paced with perfection, and I found myself cheering Cin on every time she reclaimed a bit of herself and discovered newfound strengths.
The sexual tension and attraction between her and Landers is the kind of slow burn you crave, and it delivers on making you more than ready for the tension to break. “The only time I want to see you on your knees,” he whispered with a low rumble, “is when those beautiful lips are wrapped around me.” How hot 🔥 is that?!
“You are mine.” He said the words not with possession, but in devotion. “You do not belong to me, but I . . . I belong to you.”
If you love epic adventures with found family, a morally grey MMC, magic, and an FMC coming into her own power, this needs to be added to your TBR. Oh, and did I mention, they’re dragons?!?!
