The Human (CR) Calretinin ELISA Kit measures Calretinin in samples. The plate has been pre-coated with Human CR antibody. CR present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human CR Antibody is added and binds to CR in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated CR antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human CR. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Best toy we’ve got.
Love this toy. I have had it for over a month now and there is not a bit of damage. I put her favorite soft treats in there and then break a milk bone and stuff it in there to make them stay, and it will keep her busy for hours(depending on how well I stuff it). So worth it. She is a blue healer/Rottweiler mix, very energetic and amazing at destroying toys, but this one, she is more focused on getting the treats than tearing it apart. Flawless design.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.
