Description: Recombinant Human CTSD Protein is produced by mammalian expression system in human cells. The target protein is expressed with the full length sequence of Human CTSD fused with a polyhistidine tag at the C-terminus. Form: Liquid in a 0.2 μM filtered solution of 20mM MES, 150mM NaCl, pH 5.5. Gene Symbol: CTSD Alternative Names: CPSD; Cathepsin DEntrez Gene (Human): 1509SwissProt (Human): P07339Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : SALVRIPLHK FTSIRRTMSE VGGSVEDLIA KGPVSKYSQA VPAVTEGPIP EVLKNYMDAQ YYGEIGIGTP PQCFTVVFDT GSSNLWVPSI HCKLLDIACW IHHKYNSDKS STYVKNGTSF DIHYGSGSLS GYLSQDTVSV PCQSASSASA LGGVKVERQV FGEATKQPGI TFIAAKFDGI LGMAYPRISV NNVLPVFDNL MQQKLVDQNI FSFYLSRDPD AQPGGELMLG GTDSKYYKGS LSYLNVTRKA YWQVHLDQVE VASGLTLCKE GCEAIVDTGT SLMVGPVDEV RELQKAIGAV PLIQGEYMIP CEKVSTLPAI TLKLGGKGYK LSPEDYTLKV SQAGKTLCLS GFMGMDIPPP SGPLWILGDV FIGRYYTVFD RDNNRVGFAE AARLVDHHHH HH 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 : 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.
