|
UniProt ID: | P09038 + 7 aa of propeptide |
|
Formulation: | Lyophilized from 10mM sodium phosphate, 75mM NaCl, pH 7.5. Sterile filtered. |
|
Purity: | ≥95% (Reducing and Non-reducing SDS-PAGE) |
|
Endotoxin Content: | ≤1 EU/μg protein measured by kinetic LAL analysis. |
|
Appearance: | White lyophilized (freeze-dried) powder. |
|
Biological Activity: | The activity is determined by the dose-dependent proliferation of mouse BALB/c 3T3 cells which is typically observed at concentations <1ng/ml. |
|
Reconstitution: | When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions. |

|
Use/Stability: | It is recommended that a carrier protein (0.1% HSA or BSA) is added for long term storage. |
|
Handling: | Centrifuge the vial before opening the cap. After reconstitution, prepare aliquots and store at -20°C. |
|
Scientific Background: | Fibroblast growth factors (FGFs) are a 22 member family of proteins known to be involved in angiogenesis, wound healing and embryonic development. As a family, they bind to heparin and signal through four receptor tyrosine kinases called, FGFR1, 2, 3 and 4. Although the mechanism remains unclear, FGF-basic 154, also known as FGF-2, is a critical component in keeping embryonic stem cells undifferentiated in cell culture systems. |
