CD4
Description The CD4 antibody recognizes the human CD4 antigen which is highly expressed on human T helper cells and thymocytes, and at lower levels on monocytes and dendritic cells. It is responsible for the recognition of the MHC Class II antigen. The CD4 antibody recognizes most thymocytes and about 65% of peripheral blood T cells. Applications The CD4 antibody can be used to identify and enumerate CD4+ cells by flow cytometry or fluorescence microscopy. This antibody is suitable for MACS® Control applications. For further details, please refer to the data sheet of the separation reagent. CD4 antibodies can be used to evaluate the transfection efficiency of cells transfected with pMACS 4.1 or pMACS 4-IRES II when using the MACSelect™ 4 Transfected Cell Selection Kits.
