HRP-1085 Recombinant Human CD79B Protein $200

Recombinant Human CD79B Protein

Product Name: Recombinant Human CD79B Protein
Catalog #:  HRP-1085
Manufacture:  LD Biopharma, Inc.

The B lymphocyte antigen receptor is a multimeric complex that includes the antigen-specific component, surface immunoglobulin (Ig). Surface Ig non-covalently associates with two other proteins, Ig-alpha and Ig-beta, which are necessary for expression and function of the B-cell antigen receptor. Human B-cell antigen receptor complex-associated protein b chain (CD79B) gene encodes the Ig-beta protein of the B-cell antigen component. Alternatively spliced transcript variants encoding different isoforms have been described.

Full-length extracellular domain of human human CD79B cDNA (29 – 159aa, derived from BC032651) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
