分子别名(Synonym):CTSS,MGC3886种属(Species):Human表达系统(Expressed Host):HEK293 Cells制剂(Buffer):Lyophilized from sterile PBS, pH 7.4分子量(Molecule Mass):The secreted recombinant human CTSS consists of 326 amino acids with the predicted molecular mass of 37 kDa as estimated by SDS-PAGE under reducing conditions.内毒素(Endotoxin):<1.0 EU per μg by the LAL method.生物活性(Activity):Measured by its ability to cleave a fluorogenic peptide substrate, (7-methoxycoumarin-4-yl) acetyl-Arg-Pro-Lys-Pro-Val-Glu-Nva-Trp-Arg-Lys (2, 4-dinitrophenyl)-NH2 (RCat:D Systems, Catalog#ES002). Cleavage of ES002 can be measured using excitation and emission wavelength at 320 nm and 405 nm, respectively.表达区间(Protein Construction):A DNA sequence encoding the pro form of human CTSS (NP_004070.3) (Ser 2-Ile 331) with a carboxy-terminal polyhistidine tag was expressed.存储条件(Storage):For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.运输条件:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
