Recombinant human CD8 beta protein
CD8B, also known as T-cell surface glycoprotein CD8 beta chain isoform 5, is a cell surface transmembrane glycoprotein. This protein serves as a co-receptor for the T cell receptor (TCR) . It found on most cytotoxic T lymphocytes that mediates efficient cell to cell interactions within the immune system. CD8 forms a dimer, consisting of a pair of CD8 chains. The most common form of CD8 is composed of a CD8-alpha and CD8-beta chain. Both members of the immunoglobulin superfamily with an immunoglobulin variable (IgV) -like extracellular domain connected to the membrane by a thin stalk, and an intracellular tail. Recombinant human CD8B, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
