| Synonyms | HBGH-2, HBGF-2, Prostatropin, FGF-2, FGB-b. |
| Introduction | FGF-basic is a member of the fibroblast growth factor （FGF） family. FGF family members bind heparin and possess broad mitogenic and angiogenic activities. This protein has been implicated in diverse biological processes, such as limb and nervous system development, wound healing, and tumor growth. The mRNA for this gene contains multiple polyadenylation sites, and is alternatively translated from AUG and non-AUG （CUG） initiation codons resulting in five different isoforms with distinct properties. The CUG-initiated isoforms are localized in the nucleus and are responsible for the intracrine effect, whereas, the AUG-initiated form is mostly cytosolic and is responsible for the paracrine and autocrine effects of this FGF. The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. there are differences in the tissue distribution and concentration of these 2 growth factors. |
| Description | Fibroblast Growth Factor-basic Mouse Recombinant （FGF-2） produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 145 amino acids and having a molecular mass of 16320 Dalton. The FGF-2 is purified by proprietary chromatographic techniques. |
| Source | Escherichia Coli. |
| Physical Appearance | Sterile Filtered White lyophilized （freeze-dried） powder. |
| Formulation | FGF-b was lyophilized from 5mM NaP, pH7.5 and 50mM NaCl. |
| Solubility | It is recommended to reconstitute the lyophilized Fibroblast Growth Factor ? in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Fibroblast Growth Factor-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF-basic 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. |
| Purity | Greater than 95.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE. |
| Amino acid sequence | The sequence of the first six N-terminal amino acids was determined and was found to be Met-Pro-Ala-Leu-Pro-Glu. |
| Biological Activity | The ED50 range= 0.1ng/ml, determined by the dose-dependant proliferation of BALB/3T3 cells. |
| 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 （InliGenetics）. 2. Analysis by RP-HPLC, using a calibrated solution of FGF2 as a Reference Standard. |
| Usage | ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
