    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.

  • 蛋白标签：
    Tag type will be determined during the manufacturing process.
    The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
  • 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：
    Endonuclease that cooperates with the MRN complex in processing meiotic and mitotic double-strand breaks by allowing the endonucleolytic removal of rec12 from the break sites and ensuring both resection and intrachromosomal association of the broken ends. Required for the formation of RPA-coated single strand DNA adjacent to the DSBs where it functions together with the MRN complex in 5'- 3' resection. Required for the repair of programmed meiotic DSBs. Involved also in an rhp51 recombinase-dependent recombinational repair pathway.

    1. CtIP/Ctp1/Sae2/Com1 role in removal of DNA double strand breaks through DSB repair by homologous recombination is reviewed. PMID: 28623092
    2. a mre11 mutant defective in endonucleolytic activity, the same mutant lacking Ctp1, or the triple mutant also lacking the putative hairpin nuclease Pso2 showed wild-type levels of repair. Thus, MRN (Mre11-Rad50-Nbs1)may act to recruit the hairpin opening activity that allows subsequent repair PMID: 28292918
    3. The s concludes that the intracellular Ctp1 C-terminal portion is essential for clipping, while the N-terminal portion is sufficient for DNA double-strand break end-resection. PMID: 26130711
    4. Tetrameric Ctp1 coordinates DNA binding and DNA bridging in DNA double-strand-break repair. PMID: 25580577
    5. these data propose that release of the MRN complex and Ku from DNA ends by Mre11 nuclease activity and Ctp1 is a critical step required to expose ssDNA for replication protein A localization and ensuing homologous recombination repair. PMID: 21931565
    6. In fission yeast, found only one class of oligonucleotides bound to Rec12 ranging in length from 17 to 27 nucleotides. Ctp1, Rad50, and the nuclease activity of Rad32, the fission yeast homolog of Mre11, are required for endonucleolytic Rec12 removal. PMID: 19911044
    7. These data suggest that regulation of Ctp1 underlies cell-cycle control of homologous recombination. PMID: 17936710
    8. This study demonstrates for the first time that Mre11 (Schizosaccharomyces pombe Rad32(Mre11)) nuclease activity is required for the removal of Rec12(Spo11). PMID: 19139281
    9. Schizosaccharomyces pombe Rad32(Mre11) nuclease activity is involved in the removal of both Top2 from 5' DNA ends as well as Top1 from 3' ends in vivo and a ctp1(CtIP) deletion is defective for Top2 removal but overproficient for Top1 removal. PMID: 19150433
    10. The Mre11-Rad50-Nbs1 S-phase checkpoint role is separate from its Ctp1- and resection-dependent role in double-strand break repair. PMID: 19211838
    11. Study finds that in the presence of the MRN (Rad32-Rad50-Nbs1) complex efficient recombination requires Ctp1, the ortholog of the nuclease Sae2, but not the nuclease activity of MRN. PMID: 19470480
    12. Rad32 nuclease has the catalytic site for Rec12-oligonucleotide generation and is activated by Ctp1, which plays an additional role in meiotic recombination. PMID: 19752195
    13. Tethering of Ctp1 to a flexible Nbs1 arm suggests a mechanism for restricting DNA end processing and homologous recombination activities of Sae2/Ctp1/CtIP to the immediate vicinity of double-strand breaks. PMID: 19804755
