Monoclonal Rat Purified IP IH FC
CD4/L3T4 is a type I transmembrane glycoprotein expressed on most thymocytes and the helper/inducer subpopulation of mature T lymphocytes of all mouse strains tested (1,2). CD4 has also been detected at low density on pluripotent hematopoietic stem cells, bone marrow myeloid precursors, and intrathymic lymphoid precursors (3-6). The CD4 antigen functions as a co-receptor, interacting with class II major histocompatability complex (MHC) molecules in the recognition of foreign antigens by T cells (1,2). In vivo and in vitro treatment with the effectively depletes CD4+ cells (7,8). The mAb also blocks helper T cell responses to MHC class II antigens, including cytolysis, proliferation, allogeneic B cell help, and release of lymphokines (1,8-13).
Catalog #C2255-31H
ApplicationsSuitable for use in Flow Cytometry, Immunoprecipitation, Immunohistochemistry, In vivo and in vitro depletion of CD4+ cells, Inhibition of T helper function and Fractionation of CD4+ cells. Other applications not tested.
Recommended DilutionFlow Cytometry: 0.2ug labels 10e6 cells

Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for at least 12 months at 4°C. Freezing R-Phycoerythrin, Cyanine 5.5 (PE/Cy5.5) conjugates will result in a substantial loss of activity. PE/Cy5.5 conjugates are sensitive to light.
