HGF Human, CHO

Scatter Factor (SF), Hepatopoietin (HPTA), HGF.

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 and may, therefore, also modulate hematopoiesis.

Hepatocyte Growth Factor Human Recombinant produced in CHO is a heterodimer, non-glycosylated, polypeptide chain consisting an a-chain of 463 amino acids and b-chain of 234 having a total molecular mass of approximately 75kDa.
The HGF is purified by proprietary chromatographic techniques. 

Sterile Filtered White lyophilized (freeze-dried) powder.

The protein was lyophilized from a concentrated (1.4mg/ml) solution containing Phosphate-Buffered Saline with 0.02% Tween 80, pH 7.4.

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.

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.

Greater than 97.0% as determined by SDS-PAGE.

Agrees with the sequence of native human HGF.

The ED₅₀, calculated by the dose-dependant proliferation of monkey 4MBr-5 indicator cells was found to be 20-40 ng/ml.
