Biological Activity
The activity as calculated by the dose-dependant proliferation of BALB/3T3 cells was found to be > 1ng/ml, corresponding to a specific activity of 1,000,000 units/mg.
Description
Fibroblast Growth Factor-basic Mouse Recombinant (FGF-2) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 146 amino acids and having a molecular mass of 16320 Dalton.
The FGF-2 is purified by proprietary chromatographic techniques.
Formulation
FGF-b was lyophilized from 5mM Na2PO4, pH7.5 and 50mM NaCl.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein content
Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.885 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 FGF2 as a Reference Standard.
Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility
It is recommended to reconstitute the lyophilized Fibroblast Growth Factor ? in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Source
Escherichia Coli.
Stability
Lyophilized Fibroblast Growth Factor-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution FGF-basic should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
