      Avi-tag Biotinylated

      E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

    • 产品提供形式:
      Lyophilized powder
      Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
    • 复溶:
      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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
    • 储存条件:
      Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
    • 保质期:
      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.
    • 货期:
      Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
      Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
    • 注意事项:
      Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

    • 功能:
      Converts retinaldehyde to retinoic acid. Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Can metabolize octanal and decanal, but has only very low activity with benzaldehyde, acetaldehyde and propanal. Displays complete lack of activity with citral.

      1. The authors findings indicate that the SNP rs4238326 in ALDH1A2 gene may potentially modify individual susceptibility to knee OA in the Chinese population. PMID: 28089900
      2. high transcription activities of ALDH1A2, ALDH1A3 and ALDH1L1 predicted worsen overall survival in gastric cancer patients PMID: 27015121
      3. Data show that hRALDH2 is not inhibited by its oxidation product, all-trans-RA, suggesting the absence of a negative feedback regulatory loop. Expression of the Raldh2 gene is known to be regulated by RA itself, suggesting that the main regulation of the hRALDH2 activity level is transcriptional. PMID: 27001866

      14. ALDH1A2 protein was effective in AraC resistance. ALDH1A2 knock-down induced sensitivity to AraC treatment in K562AC cells. ALDH1A2 overexpressed K562S cells acquired the AraC resistance. Ara-C-resistant patients had increased ALDH1A2. PMID: 23507523
