Technical Data
Hepatocyte Growth Factor, Recombinant, Human (HGF, Scatter Factor, SF, Hepatopoietin A)
Molecular Biology Storage: -20CShipping: RT
Hepatocyte Growth Factor (HGF) is a multifunctional growth factor which regulates both cell growth and cell motility. It exerts a strong mitogenic effect on hepatocytes and primary epithelial cells. HGF synergizes with Interleukin-3 and GM-CSF to stimulate colony formation of hematopoietic progenitor cells in vitro. It may modulate hematopoiesis.
Recombinant Human HGF is a heterodimer, non-glycosylated, polypeptide chain consisting an alpha-chain of 463aa and beta-chain of 234aa having a total molecular mass of 80kD.

Agrees with the seqeunce of native human HGF.

0.1ng/ug (IEU/ug) of HGF.

Dimers and Aggregates:
< 1% as determined by silver-stained SDS-PAGE gel analysis.

Biological Activity:
Hepatocyte Growth Factor is fully biologically active when compared to standards. The ED50, calculated by the dose-dependent proliferation of monkey 4MBr-5 indicator cells, was found to be 20-40ng/ml.

Protein Content:
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280nm using the absorbency value of 1.83 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of HGF as a Reference Standard.

Storage and Stability:
Lyophilized powder may be stored at 4C for short-term only. Reconstitute to nominal volume by adding sterile dH2O, 0.1% HSA or BSA. Aliquot and store at -20C. Reconstituted product is stable for 24 months at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
Source: Human, recombinant protein expressed by Baculovirus Infected High-5 cells
Purity: 98% by by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified. Endotoxin: < 0.1ng/ug (IEU/ug).

Form: Supplied as a lyophilized powder. Reconstitute in sterile dH2O, 0.1% HSA or BSA to a concentration > 0.1mg/ml. Can be further diluted to other aqueous solutions.
