Anti-CD4 (Tac antigen, p55, Interleukin 2 Receptor alpha, IL2Ra, T Cell Growth Factor Receptor), FIT

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. Applications:  Flow cytometry 1-3,  Immunohistochemistry (acetone-fixed, frozen tissue sections),  Immunoprecipitation 1, Recommended Dilution: Flow Cytometry: < 1ug/10e6 cells, Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20°C or colder. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
