CD4 is expressed on the surface of T helper cells, regμlatory T cells, monocytes, macrophages, and dendritic cells, and plays an important role in the development and activation of T cells. On T cells, CD4 is the co-receptor for the T cell receptor (TCR), and these two distinct structures recognize the Antigen–Major Histocompatibility Complex (MHC). Specifically, the D1 domain of CD4 interacts with the β2-domain of the MHC class II molecμle. CD4 ensures specificity of the TCR–antigen interaction, prolongs the contact between the T cell and the antigen presenting cell, and recruits the tyrosine kinase Lck, which is essential for T cell activation.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IHC, IF\/ICC\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: T-cell surface glycoprotein CD4, T-cell surface antigen T4\/Leu-3, CD4\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodification\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Recombinant protein of human CD4.
