Mouse Anti-Chicken CD28

ANTIGEN DESCRIPTION
Chicken CD28 antigen is a type I transmembrane monomeric glycoprotein which does not contain the cysteine residues that form disulfide-linked covalent homodimers found in the mammalian counterpart. This may reduce the avidity of binding to individual ligand molecules expected to be present on Ag presenting cells. Peripheral γδ + T cells are CD28-negative.[1] Monoclonal antibodies against CD28 have a costimulatory effect on T cells stimulated by phorbol myristate acetate (PMA), concanavalin A or MAbs against the avian T cell receptor (TCR). Both Vβ1- and Vβ2-expressing cells respond equally well to stimulation with anti-CD28 in combination with PMA. These responses are resistant to cyclosporin A, but inhibited by herbimycin A, suggesting that CD28 employs a signalling pathway at least partly distinct from that triggered by TCR/CD3.[2] MAb AV7 also reacts with turkey CD28 as demonstrated by flow cytometry and immunoprecipitation/Western blotting.[3]

NOTE: *SpectralRedTM (SPRD) is a tandem conjugate of R-phycoerythrin and CYTM5. It was developed as a reagent for 3-color flow cytometry on instruments with only 488 nm excitation source. It requires minimal (0-2%) FL2/FL3 compensation.
