FGF basic, or bFGF (fibroblast growth factor basic), initiates at an alternative CUG codon, marking a distinctive feature in translational initiation. This alternative start codon plays a pivotal role in regulating the expression and functional properties of FGF basic. FGF basic/bFGF Protein, Human (P. pastoris, N-His) is the recombinant human-derived FGF basic/bFGF protein, expressed by P. pastoris , with N-6*His labeled tag.
