Recombinant Human FGF-basic (154 a.a.)

Product Details

Catalogue Number: 100-18B
Recombinant Human FGF-basic (154 a.a.)

FGF-basic is one of 23 known members of the FGF family. Proteins of this family play a central role during prenatal development, postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-basic is a non-glycosylated, heparin-binding growth factor that is expressed in the brain, pituitary, kidney, retina, bone, testis, adrenal gland, liver, monocytes, epithelial cells and endothelial cells. FGF-basic signals through FGFR 1b, 1c, 2c, 3c and 4. Recombinant Human FGF-basic is a 17.2 kDa protein consisting of 154 amino acid residues.
Qualified for stem cell use.

Existing reviews
Excellent for iPS endothelial differentiation
Yet another excellent product by PeproTech! This recombinant human FGF is used at 20ng/mL with VEGF for iPS endothelial (EC) differentiation to generate high quality ECs.

Very good for stem cell maintenance
Very good product for human stem cell and cancer stem cell maintenance and proliferation, of higher quality than similar product of competitors!

Another great iPSC differentiation growth factor!
I have found this product to remain exceptionally stable in media and give good, reproducible results when I am differentiating human iPSCs. Plus, the product ships quickly (which is important when I realize I am running low on growth factors). Thank you Peprotech for quality products and fast service!

FGF, human basic recombinant, E. coli
Using the FGF in culture medium now for 6 years and very satisfied. Good quality and good customer support from Peprotech. Keep up the good work !

Great recombinant protein
Works very nicely in combination with EGF to keep mouse ESC-derived NPCs alive and proliferating in culture (at 10 ng/ml concentration). Highly recommend.
