Anti-CD4, clone Okt 04, Phycoerythrin conjugated

Phycoerythrin conjugated CD4 Monoclonal Antibody was purified from tissue culture supernatant via affinity chromatography and is directed against human CD4. Reactivity is observed against human CD4, Cynomolgus, Rhesus, and chimpanzee. This antibody recognizes a different epitope, and thus does not block binding of clone RPA-T4. Cross reactivity with CD4 from other sources has not been tested. Anti-CD4 is conjugated with PE under optimal conditions and the solution is free of unconjugated PE. Protein function: Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts. [The UniProt Consortium]
