Description：Recombinant Human SERPINB5 Protein is produced by E. coli expression system and the target gene encoding Met1-Ser231 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：SERPINB5Alternative Names：PI5; Serpin B5; Maspin; Peptidase inhibitor 5; PI-5 Entrez Gene (Human)： 5268; SwissProt (Human)： P36952; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MDALQLANSA FAVDLFKQLC EKEPLGNVLF SPICLSTSLS LAQVGAKGDT ANEIGQVLHF ENVKDVPFGF QTVTSDVNKL SSFYSLKLIK RLYVDKSLNL STEFISSTKR PYAKELETVD FKDKLEETKG QINNSIKDLT DGHFENILAD NSVNDQTKIL VVNAAYFVGK WMKKFPESET KECPFRVNKV CGAACSSKRS PIIDVKNDRD RVGHKSIPMR NLRARPAKCL SDirections 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.
