Product Description Recombinant Human FGF21 Protein is expressed from HEK293 with His tag at the N-Terminus.It contains His29-Ser209.

Product Background

Fibroblast growth factor 21 (FGF21) is a peptide hormone that is synthesized by several organs and regulates energy homeostasis. Excitement surrounding this relatively recently identified hormone is based on the documented metabolic beneficial effects of FGF21, which include weight loss and improved glycemia.
