The Bovine CXCL4/PF4 ELISA kit is a sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Cattle PF4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Cattle PF4. 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 Cattle PF4, 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 Cattle PF4 in the samples is then determined by comparing the OD of the samples to the standard curve.

My dogs favorite toy
Size: Small
My dog loves these! She has a small mouth and not many balls fit in her mouth when we play fetch. The only thing is that she can't make the balls squeak on her own, it does take pressure. However, maybe that's a plus if you don't wanna listen to squeezing all day haha. They are durable, very bouncy even in the dirt. Great price fun toy!

My dog loves them...but
Size: Small
The ball is firm, durable and bounces well, but the squeaker is a disappointment. My 16 lb chihuahua doxie mix is obsessed with squeaky toys. I bought the small size which is a good fit. These balls are a bit firm and hard to squeak but she is still able to squeak them endlessly. The squeaker only lasts a couple of weeks then it's just a ball that she ignores.
