| Description |
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. |

P14210 HGF_HUMAN; |
| Produced in |
A DNA 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. |
| MW |
Under reducing conditions, the HGF protein migrates as a broad band between 80 and 110 kDa in SDS-PAGE due to post-translational modifications, in particular glycosylation. The unmodified HGF has a predicted monomeric molecular mass of
79.7 kDa.
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 |
| Purity |
>95%, as determined by SDS-PAGE and visualised by Coomassie Brilliant Blue |
| Biol. activity |
The ED50 of HGF is typically 20 - 40 ng/ml as measured in a cell proliferation assay
using the human HepG2 cell line. |
| Form |
The HGF formulation consists of 0-30% carbohydrate by weight. When reconstituted in 0.5 ml sterile phosphate-buffered saline, the solution will contain 1% human serum albumin (HSA) and 10% trehalose. |
| Reconstitution |
It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. |
| Storage |
Lyophilised products should be stored at 2 to 8°C. Following reconstitution short-term
storage at 4°C is recommended, and longer-term storage of aliquots at -18 to -20°C.
Repeated freeze thawing is not recommended. |
