The Human (CD28) T-cell-specific Surface Glycoprotein Cd28 ELISA Kit measures T-Cell-Specific Surface Glycoprotein Cd28 in samples. The plate has been pre-coated with Human CD28 antibody. CD28 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human CD28 Antibody is added and binds to CD28 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated CD28 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human CD28. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Dog likes some
Size: Extra Small, Color: Blue
Puppy will chew on this but not favorite. Over time it gets sharp pieces and dog could ingest. Not sure how safe for a small dog. Affordable but not long lasting.

Perfect for light/moderate chewers
Size: Extra Small, Color: Blue, Size: Extra Small, Color: Blue
My dog wouldn’t stop biting on the toddlers plastic dinosaur toys, so I got him this because it’s similar to plastic. But not hard enough to where it could damage his gums, also not soft enough to break apart. It’s perfect and he’s very happy with it. My dog is 6 LB toy poodle for reference, I would say this is suitable for small dogs. I saw reviews saying that their dog absolutely destroyed it immediately, but then in the review pictures their dogs were baby bulldogs/german shepards! This isn’t meant for breeds like that, but if you have a smaller dog with smaller teeth then this is ideal.
