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.
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.
Source: E.Coli.

Specificity: The amino acid sequence of the recombinant Human REG 1 alpha is 100% homologous to the amino acid sequence of the Human REG 1 alpha without signal sequence.
Purification Method: Two-step procedure using affinity Ni-NTA chromatography and size exclusion chromatography.
Purity: >95% (SDS-PAGE analyzed).
Formulation: Sterile filtered and lyophilized from 0.5 mg/ml in 5mM Tris, 25mM NaCl, pH 7.5.
Reconstitution: Add 0.2 ml of deionized H2O and let the lyophilized pellet dissolve completely. Storage: Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.
Stability/Shelf Life: The lyophilized protein remains stable until the expiry date when stored at -20°C.
Applications: Western blotting, ELISA.
