Description:
Fibroblast Growth Factor-2 Human Recombinant (FGF-2) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 155 amino acids and having a molecular mass of 17353 Dalton.
The FGF-b is purified by proprietary chromatographic techniques.
Synonyms:
Prostatropin, HBGH-2, HBGF-2, FGF-2, FGF-b.
Source:
Escherichia Coli.

MSAKS.
Purity:
Greater than 96.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized Fibroblast Growth Factor Basic in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The protein was lyophilized from a concentrated (1mg/ml) solution in PBS, pH 7.4.
Stability:
Lyophilized Fibroblast Growth Factor-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution FGF-b should be stored at 4 °C between 2-7 days and for future use below -18 °C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Activity:
The ED50, calculated by the dose-dependant proliferation of BAF3 cells expressing FGF receptors (measured by 3H-thymidine uptake) is <0.5 ng/ml, corresponding to a specific activity of 2,000,000 Units/mg.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein Content:
Protein quantitation was carried out by two independent methods
1. UV spectroscopy at 280 nm using the absorbency value of 0.8511 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of Fibroblast Growth Factor-b as a Reference Standard.
Usage:
