HTF-0167 Recombinant Human Oncogenic cMyc-11R Protein $300

Recombinant Human Oncogenic cMyc-11R Protein

Product Name: Recombinant Human Oncogenic cMyc-11R Protein
Catalog #:  HTF-0167
Manufacture:  LD Biopharma, Inc.

cMyc gene encodes for a transcription factor that is believed to regulate expression of 15% of all gene in the cell, through binding on Enhancer Box sequences (E-boxes) and recruiting histone acetyltransferases (HATs). cMyc belongs to Myc family of transcription factors, which also includes N-Myc, and L-Myc. Myc family transcription factors contain the bHLH/LZ ( basic helix-loop-helix Leucine Zipper) domain. Wild type cMyc expression and activity are tightly regulated at many levels with a typical half-life of 30 min, but its mutant form (T58A) can alter its stability, dramatically enhance cMyc activity. It has been shown that c-Myc combined with Oct4, Sox2 and Klf4 was able to induce pluripotency in both mouse and human fibroblast cells. This mutant cMyc protein may provide better efficiency in PiPS generation.

Recombinant human oncogenic cMyc-11R 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 8 µg/ml may be used for protein derived iPS (PiPS) generation when combined with Oct4-11R, Sox2-11R and Klf4-11R.
