HGF, Recombinant, Mouse (Scatter Factor (SF), Hepatopoietin (HPTA))

HGF is a mesenchymally derived potent mitogen for mature parenchymal hepatocyte cells and acts as a growth factor for a broad spectrum of tissues and cell types.HGF signals through a transmembrane tyrosine kinase receptor known as MET.Activities of HGF include induction of cell proliferation, motility, morphogenesis, inhibition of cell growth, and enhancement of neuron survival.HGF is a crucial mitogen for liver regeneration processes, especially after partial hepatectomy and other liver injuries.Human and murine HGF are cross-reactive.Murine HGF is expressed as a linear 728 amino acid polypeptide precursor glycoprotein.Proteolytic processing of this precursor generates the biologically active form of HGF, which consists of two polypeptide chains (alpha-chain and beta-chain) held by a single disulfide bond resulting in formation of a biologically active heterodimer.The alpha-chain consists of 463 amino acid residues and four kringle domains.The beta-chain consists of 233 amino acid residues.\n\nBiological Activity:\nDetermined by the dose-dependent stimulation of the proliferation of mouse IMCD3 cells using a concentration range of 10-20ng/ml.\n\nAA Sequence:\nAlpha chain: QKKRRNTLHE FKKSAKTTLT KEDPLLKIKT KKVNSADECA NRCIRNRGFT FTCKAFVFDK SRKRCYWYPF NSMSSGVKKG FGHEFDLYEN KDYIRNCIIG KGGSYKGTVS ITKSGIKCQP WNSMIPHEHS FLPSSYRGKD LQENYCRNPR GEEGGPWCFT SNPEVRYEVC DIPQCSEVEC MTCNGESYRG PMDHTESGKT CQRWDQQTPH RHKFLPERYP DKGFDDNYCR NPDGKPRPWC YTLDPDTPWE YCAIKTCAHS AVNETDVPME TTECIQGQGE GYRGTSNTIW NGIPCQRWDS QYPHKHDITP ENFKCKDLRE NYCRNPDGAE SPWCFTTDPN IRVGYCSQIP KCDVSSGQDC YRGNGKNYMG NLSKTRSGLT CSMWDKNMED LHRHIFWEPD ASKLNKNYCR NPDDDAHGPW CYTGNPLIPW DYCPISRCEG DTTPTIVNLD HPVISCAKTK QLR

For reconstituted solutions of most products, we recommend short-term storage at 4 degrees C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20 degrees C. Additional freeze/thaw cycles may cause some denaturation of the protein.
