HRP-1607 Recombinant Human CD83 Protein $300

Recombinant Human CD83 Protein

Product Name: Recombinant Human CD83 Protein
Catalog #:  HRP-1607
Manufacture:  LD Biopharma, Inc.

The protein encoded by human CD83 gene is a single-pass type I membrane protein and member of the immunoglobulin superfamily of receptors. The encoded protein may be involved in the regulation of antigen presentation in dentritic cells. The membrane-bound CD83 is a well-known surface marker for mature DC and a soluble form of CD83 protein can bind to dendritic cells and inhibit their maturation.

Recombinant extracellular domain of human CD83 extracellular domain cDNA (20 - 144 aa, derived from BC030830) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (35aa) 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.
