|Application ||FC, E|
|Calculated MW||51111 Da|
|Description||The CD4 antigen is highly expressed on human T helper cells and thymocytes, and at lower levels on monocytes and dendritic cells. This integral membrane glycoprotein of approximately 58 kDa contains four external domains (D1 to D4) that show homology to members of the immunoglobulin (Ig) superfamily. 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.|
|Immunogen||Purified recombinant fragment of human CD4 expressed in E. Coli.|
|Formulation||Purified antibody in PBS containing 0.03% sodium azide.|
|Other Names||T-cell surface glycoprotein CD4, T-cell surface antigen T4/Leu-3, CD4, CD4|
|Dilution||FC~~1/200 - 1/400|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||CD4 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.|
|Cellular Location||Cell membrane; Single-pass type I membrane protein Note=Localizes to lipid rafts. Removed from plasma membrane by HIV-1 Nef protein that increases clathrin-dependent endocytosis of this antigen to target it to lysosomal degradation. Cell surface expression is also down-modulated by HIV-1 Envelope polyprotein gp160 that interacts with, and sequesters CD4 in the endoplasmic reticulum|
