Description：Recombinant Human BIRC5 Protein is produced by E. coli expression system and the target gene encoding Met1-Asp142 is expressed.Form：Lyophilized from a 0.2 μM filtered solution of 20mM Tris, 0.1M NaCl, pH 7.5.Gene Symbol：BIRC5Alternative Names：API4; IAP4; Baculoviral IAP repeat-containing protein 5; Apoptosis inhibitor 4; Apoptosis inhibitor survivin Entrez Gene (Human)： 332; SwissProt (Human)： O15392; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGAPTLPPAW QPFLKDHRIS TFKNWPFLEG CACTPERMAE AGFIHCPTEN EPDLAQCFFC FKELEGWEPD DDPIEEHKKH SSGCAFLSVK KQFEELTLGE FLKLDRERAK NKIAKETNNK KKEFEETAKK VRRAIEQLAA MDDirections 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.
