Description：Recombinant Human CTSB Protein is produced by mammalian expression system in human cells. The target protein is expressed with full length sequence of Human Cathepsin B fused with a polyhistidine tag at the C-terminus.Form：Liquid in a 0.2 μM filtered solution of PBS, pH7.4.Gene Symbol：CTSBAlternative Names：CPSB; Cathepsin B; APP secretase; APPS; Cathepsin B1 Entrez Gene (Human)： 1508; SwissProt (Human)： P07858; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：RSRPSFHPVS DELVNYVNKR NTTWQAGHNF YNVDMGYLKR LCGTFLGGPK PPQRVMFTED LKLPASFDAR EQWPQCPTIK EIRDQGSCGS CWAFGAVEAI SDRICIHTNA HVSVEVSAED LLTCCGSMCG DGCNGGYPAE AWNFWTRKGL VSGGLYESHV GCRPYSIPPC EHHVNGSRPP CTGEGDTPKC SKICEPGYSP TYKQDKHYGY NSYSVSNSEK DIMAEIYKNG PVEGAFSVYS DFLLYKSGVY QHVTGEMMGG HAIRILGWGV ENGTPYWLVA NSWNTDWGDN GFFKILRGQD HCGIESEVVA GIPRTDQYWE KIVDHHHHHHDirections 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：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
