SPECIFICATION
Product Name
Stemfactor FGF-basic, Human Recombinant
Catalog Number
03-0002
Size
50 µg
Purity
Greater than 95% by SDS-PAGE analysis
Formulation
Lyophilized from 5 mM Tris-HCl, pH 7.5 with 150 mM NaCl.
Reconstitution
Centrifuge briefly and then reconstitute bFGF in 500 µL of 10 mM Tris, pH 7.6, to yield a stock solution of 0.1 mg/mL of bFGF. Avoid freeze-thaw cycles as it can result in loss of activity.
Storage and Stability
Stemfactor bFGF is shipped at room temperature. Lyophilized bFGF is stable for up to 6 months from date of receipt when stored at −20 °C to −80 °C. Reconstituted bFGF, at concentrations greater than or equal to 0.1 mg/mL, is stable for up to 3 months when stored at −20 °C and up to 6 months when stored at −80 °C.
Sterility
Tested to be negative forMycoplasmasp. by PCR and microbial contamination by a sterility test.
