The IL21 (Interleukin 21) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL21. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL21. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human IL21, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human IL21 in the samples is then determined by comparing the OD of the samples to the standard curve.

Size: Medium Chew Stick, Style: Peanut Butter, Size: Medium Chew Stick, Style: Peanut Butter
My pup absolutely loves it and it's helping him with teething. It doesn't break off in a bunch of big pieces, just tiny pieces. He spits out the little pieces thankfully! Very well made and smells appetizing to dogs! It definitely helps clean his teeth & the rest of his mouth!

My little Meg loves these chew bones, she sneaks in and steals them from our Golden Retriever and our Great Pyrenees. She chews the orange covering off in minutes and the under bone lasts a few weeks. The dogs steal them from each other all the time, even though I buy them each one. Highly recommend if you have a super chewer, just be mindful the orange cover is easily chewed off.

But It
Flavor Name: Peanut Butter, Size: Medium
My fur baby has his fair share of toys, but something about this one he won’t put down. Pieces fall off the ends once they chew on it for a while.
