Hepatocyte growth factor (HGF) is a member of the plasminogen related growth factor family. The HGF protein is a dimer formed from an alpha and beta subunit linked by a disulfide bond. Both subunits originate from the endoproteolytic cleavage of a common precursor which is biologically inactive. HGF is expressed in Kupffer cella and sinusoidal endothelial cells in the liver and pancreas.
Catalog #H2005-01B
SourceDNA sequence encoding the complete human Hepatocyte Growth Factor protein isoform 1 (comprising the signal peptide, alpha and beta chains) was expressed in modified human 293 cells.
Biological. ActivityThe ED50 of HGF is typically 20-40 ng/ml as measured in a cell proliferation assay using the human HepG2 cell line.
Suitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: Under reducing conditions, the HGF protein migrates as a broad band between ~80 and 110kD in SDS-PAGE due to post-translational modifications, in particular glycosylation. The unmodified HGF has a predicted monomeric molecular mass of 79.7kD. The protein separates into a number of isoforms with a pI between 6 and 9 in 2D PAGE. The unmodified HGF protein has a predicted pI of 8.2. Optimal dilutions to be determined by the researcher.
Storage and StabilityLyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O or PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C.
