Feline CD8, Mr 70 kDa (38/31 kDa under reducing conditions).<br>Feline CD8, a member of the immunoglobulin superfamily of cell surface receptors, is a type II transmembrane glycoprotein that is expressed as a heterodimer on the "suppressor/cytotoxic" subpopulation of peripheral T lymphocytes. It is present on approximately 63% of thymocytes, 9% of splenocytes, 20% of lymph node cells, and 15% of peripheral blood lymphocytes.1,2 CD8 functions as a co-receptor with MHC Class I-restricted T cell receptors in antigen recognition.
