HTF-1527 Recombinant Human GATA3 Protein $300

Recombinant Human GATA3 Protein

Product Name: Recombinant Human GATA3 Protein
Catalog #:  HTF-1527
Manufacture:  LD Biopharma, Inc.

Human GATA3 (Trans-acting T cell specific transcription factor) belongs to the GATA family of transcription factors. The protein contains two GATA-type zinc fingers and is an important regulator of T cell development and plays an important role in endothelial cell biology. GATA3 has been shown to promote the secretion of IL4, Il5, and IL13 from Th2 cells.

human GATA3 cDNA ( 442 aa, derived from BC003070 ) was constructed with codon optimization technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. It was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
