Chaperedoxin (cnoX), recombinant Escherichia coli

Organism: Escherichia coli (strain K12). Source: E.coli. Expression Region: 1-284aa. Protein Length: Full Length. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: MSVENIVNIN ESNLQQVLEQ SMTTPVLFYF WSERSQHCLQ LTPILESLAA QYNGQFILAK LDCDAEQMIA AQFGLRAIPT VYLFQNGQPV DGFQGPQPEE AIRALLDKVL PREEELKAQQ AMQLMQESNY TDALPLLKDA WQLSNQNGEI GLLLAETLIA LNRSEDAEAV LKTIPLQDQD TRYQGLVAQI ELLKQAADTP EIQQLQQQVA ENPEDAALAT QLALQLHQVG RNEEALELLF GHLRKDLTAA DGQTRKTFQE ILAALGTGDA LASKYRRQLY ALLY. Purity: Greater than 95% 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: Chaperedoxin that combines a chaperone activity with a redox-protective function. Involved in the protection against hypochlorous acid (HOCl), the active ingredient of bleach, which kills bacteria by causing protein aggregation. Functions as an efficient holdase chaperone that protects the substrates of the major folding systems GroEL/GroES and DnaK/DnaJ/GrpE from aggregation. In addition, it prevents the irreversible oxidation of its substrates through the formation of mixed disulfide complexes. After bleach stress, it transfers its substrates to the GroEL/GroES and DnaK/DnaJ/GrpE foldases. Lacks oxidoreductase activity. Reference: n/a. Function: nan
