Product Description
Recombinant salmon FGF-2 (154 aa) protein, also known as basic fibroblast growth factor (bFGF), is a key member of the fibroblast growth factor family, a 154-amino-acid protein of around 17 kDa that exists in multiple isoforms and adopts a β-trefoil fold stabilized by disulfide bonds essential for biological activity. FGF-2 plays pivotal roles in cell growth, differentiation and angiogenesis and is a significant growth factor in embryonic development, tissue repair and wound healing. In stem cell research, FGF-2 is a key component of culture media that maintains the pluripotency and self-renewal of embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), activating signaling pathways including the MAPK pathway to sustain expression of the pluripotency genes Oct4, Sox2 and Nanog, preventing differentiation and allowing expansion in vitro. FGF-2 can also be incorporated into scaffolds or hydrogels with stem cells to promote proliferation and differentiation in a three-dimensional environment, which holds great promise for cultivated salmon protocols, making salmon FGF-2 a key reagent for serum-free media development in the cellular agriculture industry.
This protein is optimized for in vivo and functional applications: low-endotoxin, tag-free, and carrier-free, supporting reproducible performance in demanding preclinical and bioactivity studies.
Species reactivity: salmon.
