Recombinant Human CD273 Protein

Product Name: Recombinant Human CD273 Protein
Catalog #:  HRP-1456
Manufacture:  LD Biopharma, Inc.

Human programmed cell death 1 ligand 2 (PD-L2, CD273) is a cell membrane protein, which involved in the costimulatory signal, essential for T-cell proliferation and IFNG production in a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation by blocking cell cycle progression and cytokine production.

Recombinant human CD273 extracellular domain cDNA (20-220 aa, derived from BC074766) 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.
