Human HGF Activator HEK293 Overexpression Lysate 产品信息

Product Description

This Human HGF Activator overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of HGF Activator protein (Cat: 10329-H08H) from the overexpression lysate was verified.

Expression Host

HEK293 Cells

Species

Human

Sequence Information

A DNA sequence encoding the human HGF activator precursor (NP_001519.1) (Met 1-Ser 655) was expressed with a fused polyhistidine-tag at the C-terminus.

Molecule Mass

The recombinant human HGF activator consists of 631 amino acids and has a predicted molecular mass of 68.2 kDa. As a result of proteolysis or autocatalysis and glycosylation, it migrates as four bands (34, 37, 65, 105 kDa) in SDS-PAGE under reducing conditions, corresponding to the active long chain, uncleaved single chain (long chain + short chain), pro doamin and the full-length pro form of HGFA respectively.

Human HGF Activator HEK293 Overexpression Lysate Usage Guide

Preparation Method

Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.

Lysis Buffer

Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.

Recommend Usage

1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.

Sample Buffer

1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).

Stability & Storage

Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.

Application

Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

HGF Activator Background Information

HGF activator (HGFA) is a serum-derived serine protease and belongs to the peptidase family S1.HGFA is responsible for the conversion of hepatocyte growth factor (HGF), from the inactive single-chain precursor to the active heterodimeric form, which is a potent mitogen, motogen, and morphogen for liver cells, epithelial cells, and endothelial cells. HGFA is synthesized and secreted by the liver and circulates in the plasma as an inactive single-chain zymogen in normal states. The zymogen is cleaved by thrombin or thermolysin through the endoproteolytic process and forms an active heterodimer linked by a disulfide bond. In turn, the active protease can be inhibited by HGFA inhibitors (HAIs) including HAI-1 and HAI-2. In addition, the HGFA zymogen acquires a strong affinity upon activation and thus may ensure the local action in tissue regeneration in liver, kidney and skin. It has been reported that activation of HGF is a critical limiting step in the HGF/SF-induced signaling pathway mediated by Met, and accordingly, aberrant expression of HGFA is implicated in tumorigenesis and progression.
