Purity: > 90% by SDS - PAGE Format: Liquid. 20mM Tris-HCl buffer (pH 6.8) containing 50% glycerol, 1mM DTT, 1mM EDTA, 0.1M NaCl. CD247, also known as T-cell surface glycoprotein CD3 zeta chain isoform 1, belongs to CD3Z / FCER1G family. The T cell receptor Zeta together, with alpha / beta and gamma / delta heterodimers. This Protein plays an important role in binding antigen recognition to multiple intracellular signaling pathways and also plays a role in assembly and expression of the TCR complex. Defects in CD247 defects can cause immune deficiencies. Immune deficiency, characterized by T cells, impaired immune responses to allogeneic antigens, tetanus toxoid and mitogen. Recombinant human CD247, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
