Agrees with the sequence of native human HGF.
The activity was assayed for scattering activity in the MDCK cell assay.The ED50 for this effect is typically at 0.5-1ng/ml corresponding to a Specific Activity of 1,00,000-2,000,000IU/mg.
The sterile protein powder (1 mg/ml) is lyophilized from a solution containing 50mM Acetic Acid.
Sterile Filtered White lyophilized (freeze-dried) powder.
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 (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of HGF as a Reference Standard.
Greater than 90.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Hepatocyte Growth Factor in sterile 18MΩ-cm H2O not less than 100ug/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 -18oC. Upon reconstitution HGF should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
