FGF basic/bFGF Protein, Human (P. pastoris, N-His)

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.

Initiation of FGF basic, also known as bFGF (fibroblast growth factor basic), occurs at an alternative CUG codon. This alternative start codon represents a distinctive feature in the translational initiation of the protein, contributing to the unique regulatory mechanisms governing the expression and functional properties of FGF basic.

Measured in a cell proliferation assay using NIH/3T3 mouse fibroblast cells. The ED₅₀ for this effect is 0.9354 ng/mL, corresponding to a specific activity is 1.07×10^6 units/mg.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0 or PBS, 6% Trehalose, pH 7.4.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
