Molecular Biology Storage: -20CShipping: RT
Recombinant corresponding to 195aa from human Fibroblast Growth Factor 19 expressed in E. coli.

Molecular Weight:

Endotoxin: ~0.1ng/ug

Biological Activity:
FGF-19 is a high affinity heparin dependent ligand for FGFR4. Embryonic regions known to express FGF-19 include skin, cartilage, retina, gall bladder and small intestine.

Storage and Stability:
Lyophilized powder may be stored at 4C for short-term only. Reconstitute to nominal volume by adding sterile ddH2O, 0.1-1% BSA, aliquot and store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
