The CD99 (Cluster Of Differentiation 99) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CD99. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CD99. 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 CD99, 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 CD99 in the samples is then determined by comparing the OD of the samples to the standard curve.

NOT for aggressive chewers!
Color: Lion, Size: Medium
My aggressive chewer had destroyed this in 3 minutes! Chewed off the ears, and chewed apart the body to try to get to the squeaker - it was in the trash 5 minutes after I gave it to him! Yes, the seams are tough, but he easily chewed around them. Don’t buy this if your dog is an aggressive chewer!

Somewhat durable.
Color: Elephant, Size: Small
My dog loves these toys, I think it's the squeaker. I've tried several and this elephant one holds up the best.

Not tough enough
Color: Elephant, Size: Small
It might be tough, but my 26 pound dog managed to rip it open in record time! The only good thing, the squeaker is a long plastic one and easier to grab before she can swallow it!

Cute and tough!
Color: Elephant, Size: Small
Update Dec 2025, still going! This toy has been the subject of much squeaking and death shakes... And more than one tug o' war... And other than looking a little dingy even after washing it's as good as new! No missing bits, no noticeable damage. I have several in the brand, both the larger version for my mastiff, and other styles for the medium-sized dogs. I started buying online because the one store that carries it moved further away. Outshines all other brands I've tried for durability and fun play. In 5years and 9 dogs only 2 have needed replacement. Worth the price!!!

Would not purchase again
Color: Gorilla, Size: Small
My yorkie tore it up in less than 5 minutes. Not as tough as I thought it would be.
