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: TPSAB1 Alternative Names: TPS1; TPS2; TPSB1; Tryptase alpha/beta-1; Tryptase-1; Tryptase I; Tryptase alpha-1Entrez Gene (Human): 7177SwissProt (Human): Q15661Purity : 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 HHH Directions 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.
