Product name Anti-CD4 antibody
Short Description Mouse monoclonal to CD4.
Description CD4 is a protein encoded by the CD4 gene which is approximately 51,1 kDa. CD4 is localised to the cell membrane and endoplasmic reticulum. It is involved in the TGF-beta pathway, PEDF induced signalling and the T-cell receptor signalling pathway. It is a membrane glycoprotein of T-lymphocytes that interacts with major histocompatibility complex class II antigens and is also a receptor for the human immunodeficiency virus. It initiates or augments the early phase of T-cell activation, and may function as an important mediator of indirect neuronal damage in infectious and immune-mediated diseases of the central nervous system. CD4 is expressed in the blood, cells of the nervous system, liver, pancreas and spleen. STJ96972 was developed from clone 11A1 and was affinity-purified from mouse ascites by affinity-chromatography using specific immunogen. This antibody detects endogenous CD4 proteins.

CD antigen CD4 antibody
Function Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.; (Microbial infection) Acts as a receptor for human immunodeficiency virus-1 . Down-regulated by HIV-1 Vpu . Acts as a receptor for Human Herpes virus 7/HHV-7 .
Post-translational Modifications Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
Cellular Localization Cell membrane. 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.

Question by: Guest on 11 Apr 2018 16:02:00
Hi, thank you for your query. Anti-CD4 antibody [STJ96972] binds to the N-terminal.
Answer by: Customer Support on 11 Apr 2018 16:04:00
I am interested in this antibody in 0.3mg size, 1mg/mL. Would it be possible to change the storage buffer to PBS and not include sodium azide?
Question by: Guest on 11 Apr 2018 12:40:00
Hello, thank you for your query. If you would like to place a custom order, the product should be at least 1 mg. There will be no additional cost for changing the storage buffer. Please contact us at for further information.
