CD8aC Antibody – Mouse

In the chicken, the CD8 molecule is present in two forms - (i) a homodimer of two alpha chains and (ii) a heterodimer of an alpha chain and a beta chain. While the vast majority of CD8+ cells in the thymus, spleen, and blood of adult chickens express both CD8alpha- and CD8beta-chains, a relatively large proportion of the CD8+ TCRgammadelta cells in the spleens of embryos and young chicks express only the alpha-chain of CD8. Among intestinal epithelial lymphocytes, the major CD8+ T cell populations present in mice are conserved but there is a population of TCRgammadelta CD8alphabeta cells in the chicken that is not found in rodents. Chicken CD8 is expressed on approximately 80% of thymocytes, 15% of blood mononuclear cells, and 50% of spleen cells but less than 1% of cells in the bursa and bone marrow. The monoclonal antibody CT-8 recognizes the CD8alpha chain and has been shown to react to a polymorphic determinant in turkey.

Small volumes of anti-CD8aC antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS679322 is an antibody targeting CD8aC. Also known as Mouse Anti-Chicken CD8a-APC. Reactive in Chicken. Host: Mouse.
