HTF-1470 Recombinant Human p53 Protein $300

Recombinant Human p53 Protein

Product Name: Recombinant Human p53 Protein
Catalog #:  HTF-1470
Manufacture:  LD Biopharma, Inc.

Human P53 gene encodes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome. Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms. Recent data indicated that intracellular delivery recombinant wild-type p53 protein in cancer cell could selectively induce tumor cell apoptosis.

Full-length human wild type p53 (393aa, derived from BC003596) gene was constructed using codon-optimization strategy as non-fusion protein and expressed in E.coli as inclusion bodies. This protein was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
