Description：Recombinant Human Galectin 9 Protein is produced by mammalian expression system and the target gene encoding Met1-Thr323 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, 5% Trehalose, 1mM EDTA, pH7.4.Gene Symbol：LGALS9Alternative Names：Galectin-9; Gal-9; Ecalectin; Tumor antigen HOM-HD-21 Entrez Gene (Human)： 3965; SwissProt (Human)： O00182; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MAFSGSQAPY LSPAVPFSGT IQGGLQDGLQ ITVNGTVLSS SGTRFAVNFQ TGFSGNDIAF HFNPRFEDGG YVVCNTRQNG SWGPEERKTH MPFQKGMPFD LCFLVQSSDF KVMVNGILFV QYFHRVPFHR VDTISVNGSV QLSYISFQPP GVWPANPAPI TQTVIHTVQS APGQMFSTPA IPPMMYPHPA YPMPFITTIL GGLYPSKSIL LSGTVLPSAQ RFHINLCSGN HIAFHLNPRF DENAVVRNTQ IDNSWGSEER SLPRKMPFVR GQSFSVWILC EAHCLKVAVD GQHLFEYYHR LRNLPTINRL EVGGDIQLTH VQTVDHHHHH 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 ddH2O. 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.
