简单介绍：
CD4Molecule(CD4)(AA26-390)(Active)protein(Histag)
详情介绍：
Characteristics This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 42.3 kDa. The protein migrates as 52-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Purity >95 % as determined by SDS-PAGE.
Sterility 0.22 μm filtered
Endotoxin Level Less than 1.0 EU per μg by the LAL method.
Background T-cell surface glycoprotein CD4 is also known as T-cell surface antigen T4/Leu-3. CD4 contains three Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. CD4 is accessory protein for MHC class-II antigen/T-cell receptor interaction. CD4 induces the aggregation of lipid rafts. CD4 is a primary receptor used by HIV-1 to gain entry into host T cells. HIV infection leads to a progressive reduction of the number of T cells possessing CD4 receptors. Therefore, medical professionals refer to the CD4 count to decide when to begin treatment for HIV-infected patients.
