Active Recombinant Human FGF2 Protein

Specification :
| Description : The protein encoded by this gene 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 non-AUG (CUG) and AUG 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. | Source : E.coli | Species : Human | Bio-activity : Measured in a cell proliferation assay using NR6R‑3T3 mouse fibroblast cells. Raines, E.W. et al. (1985) Methods Enzymol. 109:749. The ED50 for this effect is 0.1-0.6 ng/mL. The specific activity of Recombinant Human FGF basic is approximately 800 IU/μg, which is calibrated against human FGF basic WHO International Standard. | Molecular Mass : 16.5 kDa | N-terminal Sequence Analysis : Ala | Endotoxin : | Purity : >97%, by SDS-PAGE under reducing conditions and visualized by silver stain. | Storage : Avoid repeated freeze-thaw cycles.12 months from date of receipt, -20 to -70 centigrade as supplied.1 month, 2 to 8 centigrade under sterile conditions after reconstitution.3 months, -20 to -70 centigrade under sterile conditions after reconstitution. | Storage Buffer : Lyophilized from a 0.2 μm filtered solution in Tris-HCl and NaCl. | Reconstitution : Reconstitute at 0.2 mg/mL in sterile PBS.
