Technical Data
Keratinocyte Growth Factor, Recombinant, Human (KGF, Fibroblast Growth Factor 7, FGF7, FGF-7, Heparin-binding Growth Factor 7, HBGF-7)
Molecular Biology Storage: -20CShipping: Blue Ice
Recombinant corresponding to 164aa of human Keratinocyte Growth Factor expressed in E.coli is a single, non-glycosylated, polypeptide chain.

Molecular Weight:

Biological Activity:
The ED50, calculated by the dose-dependent stimulation of KGF-responsive BaF3 indicator cells (measured by 3H-thymidine uptake).

Dimers and Aggregates:

Protein Content:
Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280nm using the absorbency value of 0.9 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENEcomputer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of KGF 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: ~98% (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.
