Product Name

Aminated magnetic microspheres

Product Overview

Aminated magnetic microspheres are magnetic particles with surface modified with amino functional groups and superparamagnetic properties, which are widely used in biomedical and molecular biology research. The 1um aminated magnetic microspheres are composed of polystyrene and iron oxide nanoparticles, which are hydrophilic and biocompatible. The aminated magnetic microspheres are superparamagnetic, have fast magnetic response, good monodispersity, and ensure homogeneity of reaction and consistency of detection. The unique surface roughness structure and polymer modification make the aminated magnetic microspheres have high amine density, which can be covalently coupled with peptides, proteins, oligonucleotides, drug molecules, glycoproteins and other biological ligands under the action of special chemical reagents (e.g., glutaraldehyde), and can be used as a good base material for encapsulation, which is an important carrier tool in medical and biomolecular research.

Product Features

 

Superparamagnetism: Aminated magnetic microspheres are superparamagnetic and can be rapidly magnetised and show magnetic properties under an applied magnetic field, and then quickly lose their magnetic properties when the magnetic field is removed, facilitating manipulation and separation in biomedical applications. 

Surface Amino Functional Groups: The surface of these microspheres is rich in amino functional groups (-NH2), which can be covalently coupled with biomolecules (e.g., proteins, antibodies, oligonucleotides, etc.) via chemical cross-linking agents to enhance their functionality in biomedical applications. 

High specific surface area: Due to their nano or micron scale particle size, aminated magnetic microspheres have a high specific surface area, providing more active sites, which is suitable for immobilisation of biomolecules and catalytic reactions. 

Good biocompatibility: Aminoated magnetic microspheres are usually made of biocompatible materials that are safe to use in living organisms, reducing immune reactions and toxicity. 

Easy modification and functionalization: The surface of aminated magnetic microspheres can be modified by various chemical methods to introduce different functional groups, thus expanding their applications in biomedical fields.

Application Fields

Protein Separation and Purification: Aminated magnetic microspheres can be used for the separation and purification of proteins. By forming covalent bonds with specific amino acid residues of proteins (e.g. lysine), efficient separation of proteins is achieved. 

Cell Separation: These microspheres are also used in cell separation, where magnetic separation of cells is achieved by specific binding to molecules on the cell surface. 

Enzyme immobilisation: Amino magnetic microspheres can be used for the immobilisation of enzymes, which are covalently bonded to the surface of the microspheres, improving the stability and reusability of the enzymes. 

Immunoassay: In immunoassay, the aminated magnetic microspheres can be used as the material for the preparation of immunomagnetic beads, which can be used for immunoassay and analysis through covalent coupling with antibodies or antigens. 

Drug delivery: Aminoated magnetic microspheres can be used as drug carriers to achieve targeted drug delivery through surface modification. Under the action of an applied magnetic field, the microspheres can be guided to the diseased area, improving the efficacy of the drug and reducing side effects.

Related Information

Aminated magnetic microspheres have good hydrophilicity and monodispersity. Due to the high magnetic content, the microsphere is easy to precipitate at the bottom after a long time of placement, and can be suspended again after a short time of ultrasonic treatment or vibration before use. Sealed, avoid light, and keep at 4¡ãC Expiry date: Six months before unsealing.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Wow.
Format: Kindle
Okay I’m usually not one for stand-alone’s I’m an avid series reader but my goodness am I so happy I read this! This story was brilliant & so absolutely mesmerizing. I loved reading about each character and their struggles as well as what helped them to move forward. The ending definitely brought tears to my eyes so hard. I truly wasn’t expecting some of what happened in this story. There is about to be a spoiler I am going to reveal so please stop reading if you don’t want the spoiler !!!! ⚠️ ⛔️ ‼️ I loved that the author didn’t do what most authors do with irredeemable male characters. I truly was hoping that Nate Jr. would be apart of the pack after the way he treated Astrea bc he truly didn’t deserve it. Though I must say you did a wonderful job or redeeming him as a person. I cried my eyes out when he walked into the story. I was truly terrified he was going to be a bad guy to the end. However you truly did him such a justice by having him realize his faults & having him redeem himself in the most wonderful way. I’m so sad that he didn’t get to hear how much his brother loved him & forgave him before dying. But again you wrote that ending so beautifully & I just can’t express how much I loved this story & how you took a different route than most authors I have read have. You are a remarkable author Cinder Blaze & I thank you generously for creating such a masterpiece.

Omegaverse
Format: Kindle
I was pleasantly surprised by this omega verse book. This 1 definitely had a few new twists And I really enjoyed reading it. The main female character was a badass and awesome. She had 1 best friend I wish we could have seen a little bit more of their friendship in this book. Her relationship with the male characters was good not to contrived or super instantaneous. And we had some fun plot twists that I didn't expect. I wish we had more of a follow up on the situation with her family her background and her mother who was a wench. I would definitely recommend this book.

Wow. Just wow. An amazing read
Format: Kindle
This book was eloquently written, or should I say the authors writing style is very eloquent? I loved the characters, and the story was quite compelling. I absolutely loved the FMC, she's a BA who doesn't take any crap & gives as good as she gets. A certain person certainly got his just desserts & then some, the earlier scenes of which were quite satisfying, had me punching the air & everything haha. All in all 20/10, great read
