Recombinant Human HGF Protein(CHO)

HGF

Human hepatocyte growth factor (HGF) is a natural ligand of Met tyrosine kinase receptor, mediating cell proliferation, migration and anti-apoptosis by binding to Met receptor. HGF protein can promote the regeneration of liver and kidney cells, regulate extracellular matrix metabolism (inhibit TGF-β, promote MMP-2), and is used in the study of acute and chronic kidney disease, liver fibrosis and other diseases. HGF Protein, Human (CHO) is a recombinant human HGF protein expressed by CHO cells with tag-free.

Greater than 95% as determined by reducing SDS-PAGE. Human HGF is initially produced as a single, inactive polypeptide and is subsequently cleaved by serine proteases to generate a 69-kDa α chain and a 34-kDa β chain. The free α and β chains then combine to form an active heterodimer through the formation of disulfide bonds between cysteine residues. Under reducing conditions (SDS-PAGE), the protein exhibits apparent molecular masses of 90, 60, and 34 kDa, which correspond to the heavy α chain and the light β chain, respectively, due to glycosylation.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
