HRP-1060 Recombinant Human TIM3 Protein $300

Recombinant Human TIM3 Protein

Product Name: Recombinant Human TIM3 Protein
Catalog #:  HRP-1060
Manufacture:  LD Biopharma, Inc.

The protein encoded by T-cell immunoglobulin and mucin domain-containing protein-3 (TIM3) gene belongs to the immunoglobulin superfamily, and TIM family of proteins. CD4-positive T helper lymphocytes can be divided into types 1 (Th1) and 2 (Th2) on the basis of their cytokine secretion patterns. Th1 cells are involved in cell-mediated immunity to intracellular pathogens and delayed-type hypersensitivity reactions, whereas, Th2 cells are involved in the control of extracellular helminthic infections and the promotion of atopic and allergic diseases. This protein is a Th1-specific cell surface protein that regulates macrophage activation, and inhibits Th1-mediated auto- and alloimmune responses, and promotes immunological tolerance. Recent data indicated that TIM3 is specific therapeutic target protein for targeting AML stem cells.

Full-length extracellular domain of human TIM3 cDNA (22 – 202 aa, derived from BC063431) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
