Recombinant Human Regenerating Islet-derived 1 Alpha, His-tagged

• Cat.No.: REG1A-192H
• Product Overview: Recombinant Human REG 1 alpha (His-tagged) contains 144 amino acids and has a molecular mass of 17.8 kDa. And this protein expressed inE.Coli.

Specification

• Cat. No.: REG1A-192H
• Description: REG protein was shown to be stimulated during the regeneration of pancreatic islets. Since then, many Reg-related proteins have been identified in humans and other animals. In human, the four REG family genes, i.e., REG 1 alpha, REG 1 beta, REG-related sequence (RS) and HIP/PAP, have so far been isolated. Reg protein is a growth factor for pancreatic beta cells and also suggest that the administration of Reg protein could be used as another therapeutic approach for diabetes mellitus. human REG cDNA which encoded a 166-amino acid protein with a 22-amino acid signal peptide. The amino acid sequence of human REG protein has 68% homology to that of rat Reg protein. Reg I was found to be expressed mainly in pancreatic beta and acinoductular cells as well as gastric fundic enterochromaffin-like (ECL) cells.
