Human bFGF / FGF2 Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant bFGF / FGF2 based upon sequence from: Human
Host: QP5269 protein expressed in E. coli.
Recommended Applications: Bioactive
Application Notes: Please contact us for application specific information for QP5269. One of the most common applications of our bFGF protein has been in stem cell culture. In stem cell culture, bFGF (along with other nutrients and growth factors) is supplemented in the range of 4-10 ng/ml for systems incorporating feeder cells (eg. HFF or HPF). In systems without feeder cells, much higher concentrations (50-100 ng/ml) of bFGF are recommended.
Bioactivity Data: BioActivity: Concentrations of <5 ng/mL are sufficient to induce cell proliferation of 3T3 cells. The bioactivity acceptance criteria is set at 2 x 105 units/mg.
Monomer or Dimer: Monomer
