This antibody recognizes a conformationally-dependent epitope of CD8, a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. CD8 is a disulfide-linked dimer and exists as a CD8α homodimer or CD8α/β heterodimer (each monomer approx. 32-34 kDa).
Flow cytometry (recommended starting dilution: 1: 2500). The antibody does not react with formaldehyde-fixed cells, negative in Western Blottingapplication. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

The CD8 T cell coreceptor (monomer approx. 32-34 kDa) is expressed as αβ heterodimer on majority of MHC I-restricted conventional T cells and thymocytes and as αα homodimer on subsets of memory T cells, intraepithelial lymphocytes, NK cells and dendritic cells. Regulation of CD8β level on T cell surface seems to be an important mechanism to control their effector function. Assembly of CD8 α-β but not α-α dimers is connected with formation or localization to the lipid rafts. Recruiting triggered TCR complexes to these membrane microdomains as well as affinity of TCR to MHC I is modulated by CD8, thereby affecting the functional diversity of the TCR signaling.Synonyms: CD8 alpha chain, CD8A, MAL, T-cell surface glycoprotein CD8 alpha chain, T-lymphocyte differentiation antigen T8/Leu-2
