Description：Recombinant Human KITLG Protein is produced by E. coli. It is a single non-glycosylated polypeptide chain containing 165 amino acids with a molecular mass of 18.4 kD.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.0.Gene Symbol：KITLGAlternative Names：MGF; SCF; Kit ligand; Mast cell growth factor; MGF; Stem cell factor; SCF; c-Kit ligand Entrez Gene (Human)： 4254; SwissProt (Human)： P21583; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：MEGICRNRVT NNVKDVTKLV ANLPKDYMIT LKYVPGMDVL PSHCWISEMV VQLSDSLTDL LDKFSNISEG LSNYSIIDKL VNIVDDLVEC VKENSSKDLK KSFKSPEPRL FTPEEFFRIF NRSIDAFKDF VVASETSDCV VSSTLSPEKD SRVSVTKPFM LPPVADirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
