Recombinant Human FGF-acidic (FGF-1) is a single, non-glycosylated, polypeptide chain containing 15aa and having a molecular weight of 17.4kD. The sequence of the first five N-terminal amino acids was determined to be Met-Phe-Asn-Leu-Pro. Contains less than 1% dimers and aggregates.

Source: Recombinant Human FGF-acidic, expressed in E. coli.

Molecular weight: 17.4kD

Endotoxin: 0.1ng/ug (IEU/ug).

Activity:
The ED50 as determined by the dose-dependent proliferation of BAF3 cells expressing FGF receptors (measured by 3H-thymidine uptake) is <10ng/ml, corresponding to a specific activity of 1x10e5Units/mg.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized powder may be stored at 4C for short-term only. Stable for at least 6 months at -20C. Reconstitute with sterile deionized water to a concentration 100ug/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). 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.

Molecular Weight:
17.4kD
Source: E. coli
Purity: 95% (HPLC, FPLC, SDS-PAGE).
Form: Supplied as a lyophilized powder from 10mM Tris, pH 7.6, 100mM sodium chloride. No preservative added. Reconstitute with sterile deionized water to a concentration 100ug/ml.
