CD4 Antibody [3-4F4] (PE)

Feline CD4, a member of the immunoglobulin superfamily of cell surface receptors, is a type I transmembrane glycoprotein that is expressed on the helper/inducer subpopulation of peripheral T lymphocytes. It is present on approximately 55% of thymocytes, 15% of splenocytes, 40% of lymph node cells, and 25% of peripheral blood lymphocytes. CD4 functions as an accessory molecule in the recognition of foreign antigens in association with MHC Class II antigens by T cells.
