Description：Recombinant Human SEMA4G Protein is produced by mammalian expression system and the target gene encoding Val18-Leu680 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4.Gene Symbol：SEMA4GAlternative Names：KIAA1619; Semaphorin-4G Entrez Gene (Human)： 57715; SwissProt (Human)： Q9NTN9; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：VPGPSLRRPS RELDATPRMT IPYEELSGTR HFKGQAQNYS TLLLEEASAR LLVGARGALF SLSANDIGDG AHKEIHWEAS PEMQSKCHQK GKNNQTECFN HVRFLQRLNS THLYACGTHA FQPLCAAIDA EAFTLPTSFE EGKEKCPYDP ARGFTGLIID GGLYTATRYE FRSIPDIRRS RHPHSLRTEE TPMHWLNDAE FVFSVLVRES KASAVGDDDK VYYFFTERAT EEGSGSFTQS RSSHRVARVA RVCKGDLGGK KILQKKWTSF LKARLICHIP LYETLRGVCS LDAETSSRTH FYAAFTLSTQ WKTLEASAIC RYDLAEIQAV FAGPYMEYQD GSRRWGRYEG GVPEPRPGSC ITDSLRSQGY NSSQDLPSLV LDFVKLHPLM ARPVVPTRGR PLLLKRNIRY THLTGTPVTT PAGPTYDLLF LGTADGWIHK AVVLGSGMHI IEETQVFRES QSVENLVISL LQHSLYVGAP SGVIQLPLSS CSRYRSCYDC ILARDPYCGW DPGTHACAAA TTIANRSQGS RTALIQDIER GNRGCESSRD TGPPPPLKTR SVLRGDDVLL PCDQPSNLAR ALWLLNGSMG LSDGQGGYRV GVDGLLVTDA QPEHSGNYGC YAEENGLRTL LASYSLTVRP ATPAPAPKAP ATPGAQLAPD VRLVDHHHHH HDirections 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.
