Caspase-1 (CASP1), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 120-269aa. Protein Length: Partial. Tag Info: N-terminal GST-tagged. Target Protein Sequence: NPAMPTSSGS EGNVKLCSLE EAQRIWKQKS AEIYPIMDKS SRTRLALIIC NEEFDSIPRR TGAEVDITGM TMLLQNLGYS VDVKKNLTAS DMTTELEAFA HRPEHKTSDS TFLVFMSHGI REGICGKKHS EQVPDILQLN AIFNMLNTKN. Purity: Greater than 90% 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: Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory elent binding proteins (SREBPs). Can also promote apoptosis. Reference: A novel heterodimeric cysteine protease is required for interleukin-1 beta processing in monocytes.Thornberry N.A., Bull H.G., Calaycay J.R., Chapman K.T., Howard A.D., Kostura M.J., Miller D.K., Molineaux S.M., Weidner J.R., Aunins J., Elliston K.O., Ayala J.M., Casano F.J., Chin J., Ding G.J.-F., Egger L.A., Gaffney E.P., Limjuco G. , Palyha O.C., Raju M., Rolando A.M., Salley J.P., Yamin T.-T., Lee T.D., Shively J.E., McCross M., Mumford R.A., Schmidt J.A., Tocci M.J.Nature 356:768-774(1992). Function: Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis. Upon inflammasome activation, during DNA virus infection but not RNA virus challenge, controls antiviral immunity through the cleavage of CGAS, rendering it inactive
