Recombinant Human pDX1-11R Protein

Product Name: Recombinant Human pDX1-11R Protein
Catalog #:  HTF-0016
Manufacture:  LD Biopharma, Inc.

Human pDX1 is a transcription factor that is expressed in beta and delta cells of the islets of Langerhans and in scattered endocrine cells of the duodenum. pDX1 activates insulin, somatostatin, glucokinase, islet amyloid polypeptide and glucose transporter type 2 gene transcription. Furthermore, PDX1 plays a key role in the development of the pancreas and islet cell ontogeny. Recent publication indicats that when pDX1 combined with Ngn3 and MAFA gene, it could trans-differentiate exocrine cell to pancreatic β-cells.

Recombinant human pDX1 protein was constructed with C-terminal tag of 11 arginine domain, which efficiently delivery protein intracellularly. This protein was expressed in E. coli, refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. Incubating this protein in culture mediums at concentration of 2 -8 µg/ml may be used for pancreatic beta cell trans-differentation application when combined with Ngn3. MAFA and Pax4 proteins.
