HTF-0380 Recombinant Human HSF1-11R Protein $300

Recombinant Human HSF1-11R Protein

Product Name: Recombinant Human HSF1-11R Protein
Catalog #:  HTF-0380
Manufacture:  LD Biopharma, Inc.

The product of this human heat shock factor protein 1 (HSF1) is a heat-shock transcription factor. Transcription of heat-shock genes is rapidly induced after temperature stress. Hsp90, by itself and/or associated with multichaperone complexes, is a major repressor of this gene. Recent data demonstrated HSF1 protein plays a major role in the regulating hepatic steatosis and metabolic syndrome, which link to Hepatocellular carcinoma (HCC) development

Recombinant human HSF1 protein was constructed with C-terminal tag of 11 arginine domain, which efficiently delivery protein intracellularly. This protein was expressed in E. coli as inclusion bodies, 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 studying HCC development in vitro.
