Description

Guinea pig HELIX-II (Type II Collagen Helical Peptide) ELISA KitThe Guinea pig HELIX II (Type II Collagen Helical Peptide) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Guinea pig HELIX II. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig HELIX II and Avidin Horseradish Peroxidase (HRP) conjugate

The Guinea pig HELIX-II (Type II Collagen Helical Peptide) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Guinea pig HELIX-II. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig HELIX-II and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Guinea pig HELIX-II, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Guinea pig HELIX-II. You can calculate the concentration of Guinea pig HELIX-II in the samples by comparing the OD of the samples to the standard curve.

Good, But Not Suitable for Aggressive Chewers.
I recently ordered the Chewzzle TPR Dog Chew Bones (3-pack) and overall, they’re a good option for light to moderate chewers. The colors are bright and fun, and the textured surface seems to help with gentle teeth cleaning, which is a nice bonus. The material feels flexible yet durable enough for casual chewing sessions. My dog was immediately interested in them and got to chewing. That said, these are definitely not suitable for aggressive chewers like mine. He had ripped and bit off pieces in a matter of mins. If your dog tends to tear through toys quickly or has a strong bite, these likely won’t hold up for long. They’re better suited for small to medium dogs that enjoy softer chew toys rather than heavy-duty ones. For the price, it’s a fair value as long as you’re buying with the right expectations. Great for light chewers, but not the best choice if you need something truly tough or long-lasting.

Great set! 6 weeks in and we still use everything in this pack daily
Got this snuggle puppy set for my 10wo Goldendoodle. I gave it to her after she’d been with me (and away from her litter) for about 2 weeks, so she actually didn’t like the heartbeat, but she LOVED the pup, which was bigger than her when I got it. One particularly cold night, I stuffed glove warmers in the heart pocket for extra warmth (I don’t like to run the heat too much as it affects my sinuses). She snuggled right up to it. The shape and softness makes it her favorite sleeping companion, no matter what position she’s sleeping in. She’s now 16w and still loves this puppy, even though she’s much bigger than it now. This puppy is holding up to her mouthing/teething stage and I’ve found it easy to keep clean. She loved the wabble ball stuffed with a little kibble, but quickly mastered it. The lick mats have been a lifesaver and are used daily in this house. Love that I have a spatula just for her and they’re pretty easy to clean. This is an excellent value for what you get!

Puppy settled in quite well with it!
This was a wonderful product. We got it for our puppy and it still stays in kennel in my bedroom, the door of it open at all times so he can come and go as he pleases- I no longer leave the heart in it but he still loves it and carries it through the house, dragging it! I would very much recommend it
