The Human IL-31 ELISA kit is a sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL31. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL31. 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 IL31, 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 IL31 in the samples is then determined by comparing the OD of the samples to the standard curve.

So much sturdy fun for little dogs!
Size: Small 2"
Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

Well made, perfect size!
Size: Small 2"
My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.

Durable, bouncy, not annoying like squeaky ball & our dogs LOVE them.
Size: Small 2"
Love these and my dogs love them to! Not nearly as noisy as a squeaky ball (thank goodness) and they bounce which are dogs love. They will fetch them, and they will play by tossing it up and pouncing on it when it bounces. They literally entertain themselves with it when we aren't playing fetch. Much more durable than the round rubber / latex squeaky ball / toys.
