Description

Rat CD28 (Cluster of Differentiation 28) ELISA KitThe Rat CD28 (Cluster of Differentiation 28) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Rat CD28. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat CD28 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro

The Rat CD28 (Cluster of Differentiation 28) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat CD28. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat CD28 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat CD28, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat CD28. You can calculate the concentration of Rat CD28 in the samples by comparing the OD of the samples to the standard curve.

My dog loves this guy!!
Color: gray & pink
This is the cutest little guy and my dog loves him. He knows him by name, he is tough and holds up incredibly well. My dog can give it a good chew but no problem! Make more cute ones and we will give them all names for him to play with.

Cute and well loved.
Color: gray & pink, Color: gray & pink
My dog gives this 5 stars because she loves to destroy stuffies and this was no exception. She immediately removed the ears and tail, along with the little nubs that were supposed to be nostrils. I give is a few points because she still hasn't removed any legs. I thought it was so cute, and it is far less cute since my dog has had her way with it. She still loves it however…so it is a winner in our book. The photo is after only a couple hours of play

These toys are tough. We have a Great Dane and Sheppard that play tug of war with it no tears or rips. What’s great also the squeak is not loud and obnoxious like othe squeaky toys!
