Cathepsin W (CTSW), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 128-376aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged and C-terminal Myc-tagged. Target Protein Sequence: VPFSCDWRKV ASAISPIKDQ KNCNCCWAMA AAGNIETLWR ISFWDFVDVS VQELLDCGRC GDGCHGGFVW DAFITVLNNS GLASEKDYPF QGKVRAHRCH PKKYQKVAWI QDFIMLQNNE HRIAQYLATY GPITVTINMK PLQLYRKGVI KATPTTCDPQ LVDHSVLLVG FGSVKSEEGI WAETVSSQSQ PQPPHPTPYW ILKNSWGAQW GEKGYFRLHR GSNTCGITKF PLTARVQKPD MKPRVSCPP. Purity: Greater than 85% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: May have a specific function in the mechanism or regulation of T-cell cytolytic activity., (Microbial infection) Plays a role during influenza virus infection in lungs cells ex vivo. Acts at the level of virus entering host cytoplasm from late endosome. Reference: "Next-generation sequencing to generate interactome datasets."
