Description：Recombinant Human Tryptase alpha/beta Protein is produced by mammalian expression system and the target gene encoding Ile31-Pro275 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：TPSAB1Alternative Names：TPS1; TPS2; TPSB1; Tryptase alpha/beta-1; Tryptase-1; Tryptase I; Tryptase alpha-1 Entrez Gene (Human)： 7177; SwissProt (Human)： Q15661; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：IVGGQEAPRS KWPWQVSLRV RDRYWMHFCG GSLIHPQWVL TAAHCLGPDV KDLATLRVQL REQHLYYQDQ LLPVSRIIVH PQFYIIQTGA DIALLELEEP VNISSRVHTV MLPPASETFP PGMPCWVTGW GDVDNDEPLP PPFPLKQVKV PIMENHICDA KYHLGAYTGD DVRIIRDDML CAGNTRRDSC QGDSGGPLVC KVNGTWLQAG VVSWDEGCAQ PNRPGIYTRV TYYLDWIHHY VPKKPVDHHH HHHDirections 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.
