Description：Recombinant Human TNFSF18 Protein is produced by mammalian expression system and the target gene encoding Glu74-Ser199 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：TNFSF18Alternative Names：AITRL; GITRL; TL6; Tumor necrosis factor ligand superfamily member 18; Activation-inducible TNF-related ligand; AITRL; Glucocorticoid-induced TNF-related ligand; hGITRL Entrez Gene (Human)： 8995; SwissProt (Human)： Q9UNG2; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：ETAKEPCMAK FGPLPSKWQM ASSEPPCVNK VSDWKLEILQ NGLYLIYGQV APNANYNDVA PFEVRLYKNK DMIQTLTNKS KIQNVGGTYE LHVGDTIDLI FNSEHQVLKN NTYWGIILLA NPQFISVDHH HHHHDirections 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.
