Synonyms Scatter Factor （SF）, Hepatopoietin （HPTA）, HGF.
Introduction 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-3and GM-CSFto stimulate colony formation of hematopoietic progenitor cells in vitro and may, therefore, also modulate hematopoiesis.
Description Hepatocyte Growth Factor Human Recombinant produced in CHO is a heterodimer, non-glycosylated, polypeptide chain consisting an ?-chain of 463 amino acids and b-chain of 234 having a total molecular mass of 75kDa.
The HGF is purified by proprietary chromatographic techniques.
Source Chinese Hamster Ovary Cells.
Physical Appearance Sterile Filtered White lyophilized （freeze-dried） powder.
Formulation The protein was lyophilized from a concentrated （1mg/ml） solution containing Phosphate-Buffered Saline with 0.02% Tween 80, pH 7.4.
Solubility It is recommended to reconstitute the lyophilized Hepatocyte Growth Factor in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability Lyophilized Hepatocyte Growth Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution HGF should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
Purity Greater than 97.0% as determined by（a） Analysis by RP-HPLC.
（b） Analysis by SDS-PAGE.
Amino acid sequence Agrees with the sequence of native human HGF.
Biological Activity The ED50, calculated by the dose-dependant proliferation of monkey 4MBr-5 indicator cells was found to be 20-40 ng/ml.
Protein content Protein quantitation was carried out by two independent methods
1. UV spectroscopy at 280 nm 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 （InliGenetics）.

2. Analysis by RP-HPLC, using a calibrated solution of HGF as a Reference Standard.
Usage ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
