Fibroblast Growth Factor-basic (bFGF), also known as FGF-2, is a heparin-binding member of the FGF superfamily of molecules. Proteins of this family play a central role during prenatal development and postnatal growth and regeneration of a variety of tissues by promoting cellular proliferation and differentiation. Additionally, bFGF is a critical component of embryonic stem cell culture medium, allowing cells to remain in an undifferentiated state in serum-free medium1,2. Stemfactor bFGF is an approximate 17 kDa protein consisting of 155 amino acid residues.
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 for Mycoplasmasp. by PCR and microbial contamination by a sterility test.
