特徴

• CD4 is a cell-surface glycoprotein found on the mature helper T cells and immature thymocytes, as well as on monocytes and macrophages. (Some cytotoxic T cells have CD4 protein as well.) Normally, ~65% of T cells in the blood are CD4+ (have CD4 protein protruding from their membrane). A mature T cell with either have CD4 or CD8, but not both. During one stage of development T cells develop CD4 and CD8 receptors, but they eventually are differentiated in the thymus and become more specialized.
• Source:Recombinant protein corresponding to 365aa of human soluble CD4, expressed in Baculovirus.
• Molecular Weight:~40kD (non glycosylated), as a result of glycosylation the sCD4 migrates as a ~46kD protein on standard SDS-PAGE
• Biological Activity:Immune reactive in ELISA using CD4 in gpl2O capture ELISA assays.
