描述（Description）
FGF-4 Protein, Human is a member of the FGF family that transforms 3T3 cells with high efficiency, stimulates endothelial cell proliferation, migration, and protease production, and shows angiogenic activity.
生物活性（Bioactivity）
The ED50 is ≤1.5 ng/mL as measured by 3T3 cells, corresponding to a specific activity of ≥6.67 × 105 units/mg.

制剂（Trait）
Lyophilized from a 0.22 μm filtered solution of 50 mM HEPES, 750 mM NaCl, pH 7.5 or 50 mM HEPES, 750 mM NaCl, pH 7.5, 8% trehalose.
复溶（Reconstitution）
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
保存条件&效期（Storage & Stability）
Stored at -20°C for 2 years. 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.
运输方式(Shipping)
Room temperature in continental US; may vary elsewhere.
生物活性（Bioactivity）
Measured in a cell proliferation assay using NIH3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 0.25-1 ng/mL.
电泳（SDS-PAGE）
Greater than 95% as determined by reducing SDS-PAGE.
