Description: Recombinant Human SERPINB9 Protein is produced by mammalian expression system and the target gene encoding Met1-Pro376 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: SERPINB9 Alternative Names: PI9; Serpin B9; Cytoplasmic antiproteinase 3; CAP-3; CAP3; Peptidase inhibitor 9; PI-9Entrez Gene (Human): 5272SwissProt (Human): P50453Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : METLSNASGT FAIRLLKILC QDNPSHNVFC SPVSISSALA MVLLGAKGNT ATQMAQALSL NTEEDIHRAF QSLLTEVNKA GTQYLLRTAN RLFGEKTCQF LSTFKESCLQ FYHAELKELS FIRAAEESRK HINTWVSKKT EGKIEELLPG SSIDAETRLV LVNAIYFKGK WNEPFDETYT REMPFKINQE EQRPVQMMYQ EATFKLAHVG EVRAQLLELP YARKELSLLV LLPDDGVELS TVEKSLTFEK LTAWTKPDCM KSTEVEVLLP KFKLQEDYDM ESVLRHLGIV DAFQQGKADL SAMSAERDLC LSKFVHKSFV EVNEEGTEAA AASSCFVVAE CCMESGPRFC ADHPFLFFIR HNRANSILFC GRFSSPVDHH HHHH 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 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.
