HRP-1084 Recombinant Human PPBP Protein $200

Recombinant Human PPBP Protein

Product Name: Recombinant Human PPBP Protein
Catalog #:  HRP-1084
Manufacture:  LD Biopharma, Inc.

The protein encoded by human platelet basic protein (PPBP) gene is a platelet-derived growth factor that belongs to the CXC chemokine family. This growth factor is a potent chemoattractant and activator of neutrophils. It has been shown to stimulate various cellular processes including DNA synthesis, mitosis, glycolysis, intracellular camp accumulation, prostaglandin E2 secretion, and synthesis of hyaluronic acid and sulfated glycosaminoglycan. It also stimulates the formation and secretion of plasminogen activator by synovial cells.

Full-length mature form of human PPBP cDNA (35-128aa, derived from BC028217) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
