Recombinant corresponding to 155aa of human Fibroblast Growth Factor-acidic expressed in E.coli is a single, non-glycosylated,polypeptide chain.

Molecular Weight:

Biological Activity:
The ED50, calculated by the dose-dependent proliferation of BAF3 cells expressing FGF receptors (measured by 3H-thymidine uptake) is less then 10ng/ml, corresponding to a specific activity of 10Units/mg.

Dimers and Aggregates:

Protein Content:
Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280nm. 2. Analysis by RP-HPLC, using a standard solution of FGF-acidic as a Reference Standard.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O, HSA or BSA. Aliquot to avoid repeated freezing and thawing. Store 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.

Molecular Weight:
Purity: ~95% (RP-HPLC, Anion-exchange FPLC, SDS-PAGE) Endotoxin: 0.1ng/ug (IEU/ug)
Concentration: ~1mg/ml
Form: Supplied as a lyophilized powder. No preservative added. Reconstitute with sterile dH2O, 0.1% HSA or BSA to 0.1mg/ml.
