Recombinant Human CD8B Protein, C-His-tagged

• Cat.No.: CD8B-177H
• Product Overview: Recombinant Human CD8B Protein with C-His tag was expressed in E. coli.

Specification

• Description: The T cell receptor (TCR) is a heterodimer composed of either a and b or γ and δ chains. CD3 chains and the CD4 or CD8 co-receptors are also required for efficient signal transduction through the TCR. The TCR is expressed on T helper and T cytotoxic cells that can be distinguished by their expression of CD4 and CD8. T helper cells express CD4 proteins and T cytotoxic cells display CD8. CD8 (also designated Leu 2 or T8), a cell surface glycoprotein, is a two chain complex (aa or ab) receptor that binds class I MHC molecules presented by the antigen-presenting cell (APC). A primary function of CD8 is to facilitate antigen recognition by the TCR and to strengthen the avidity of the TCR-antigen interactions. An additional role for CD8-expressing T cells may be to maintain low levels of HIV expression.
