Description
The RM4-5 monoclonal antibody binds to mouse CD4, a 55-kDa protein which acts as a co-receptor for the T cell receptor (TCR) in its interaction with major histocompatibility complex (MHC) class II molecules on antigen-presenting cells. The extracellular domain of CD4 binds to the beta2-domain of MHC class II, while its cytoplasmic tail provides a binding site for the tyrosine kinase lck, facilitating the signaling cascade that initiates T cell activation. CD4 is typically expressed on thymocytes, certain mature T cell populations such as Th17 and T regulatory (Treg) cells, as well as on dendritic cells. The RM4-5 antibody is widely used as a phenotypic marker for CD4 expression. If used together, the RM4-5 antibody and an alternative antibody, Anti-Mouse CD4 clone GK1.5, will "compete" for binding, i.e. RM4-5 antibody is able to block GK1.5 antibody binding to cells. In contrast, RM4-5 antibody does not block the binding of Anti-Mouse CD4 clone RM4-4 to cells.
The antibody was purified by affinity chromatography and conjugated to the fluorophore.
