Human FGF-4 Protein, His Tag

Fibroblast growth factor-4 (FGF4) is expressed in embryonic stages and in adult tissues, where it plays critical roles in modulating multiple cellular functions. Fibroblast growth factor 4 (FGF4) is a multipotent growth factor and is highly expressed in various human cancers. In lung adenocarcinoma (ADC) cell lines, FGF4 could alter cell morphology, promote epithelial-mesenchymal transition-associated protein expression, and enhance cell proliferation, migration/invasion and colony initiation. In B-cell lymphoma, FGF4 secretion by cancer cells induces Jag1 expression in neighbor Endothelial cell that in turn activates Notch2 in lymphoma cells.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 19.8 kDa. The protein migrates as 23-24 kDa under reducing (R) condition (SDS-PAGE) .

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.
