    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.

  • 蛋白標簽：
    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.
  • 產品提供形式：
    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.
  • 復溶：
    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.
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    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.
  • 貨期：
    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.
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點詳情

  • 功能：
    Histone H1 protein binds to linker DNA between nucleosomes forming the macromolecular structure known as the chromatin fiber. Histones H1 are necessary for the condensation of nucleosome chains into higher-order structured fibers. Acts also as a regulator of individual gene transcription through chromatin remodeling, nucleosome spacing and DNA methylation.
  • 基因功能參考文獻：
    1. results define a network of E2F target genes as susceptible to the regulatory influence of H1.2, where H1.2 augments global association of pRb with chromatin, enhances transcriptional repression by pRb, and facilitates pRb-dependent cell-cycle arrest PMID: 28614707
    2. BRG1 participates in gene repression by interacting with H1.2, facilitating its deposition and stabilizing nucleosome positioning around the transcription start site. PMID: 27390128
    3. Results show that histones H1.2 and H1.4 were observed in MDA-MB-231 metastatic breast cancer cells. The phosphorylation at S173 of histone H1.2 and S172, S187, T18, T146, and T154 of H1.4 significantly increases during M phase suggesting that these events are cell cycle-dependent. Also, the study reports the observation of the H1.2 SNP variant A18V in MCF-10A cells. PMID: 26209608
    4. Integration with apoptotic intermediates (via C-terminal tail interactions) may constitute a more generalized function of linker histone isoforms in apoptotic cascades. PMID: 24525734
    5. Histone H1.2-T165 post translational modifications are dispensable for chromatin binding and cell proliferation while the H1.4-K26 modifications are essential for proper cell cycle progression. PMID: 24873882
    6. H1.2 interacts with Cul4A and PAF1 to activate developmental regulatory genes. PMID: 24360965
    7. H1.2 is less abundant than other histone H1 variants at the transcription start sites of inactive genes, and promoters enriched in H1.2 are different from those enriched in other histone H1 variants and tend to be repressed. PMID: 24476918
    8. Mutations in linker histone genes HIST1H1 B, C, D, and E; OCT2 (POU2F2); IRF8; and ARID1A underlying the pathogenesis of follicular lymphoma. PMID: 24435047
    9. These data suggest that p53 acetylation-H1.2 phosphorylation cascade serves as a unique mechanism for triggering p53-dependent DNA damage response pathways. PMID: 22249259
    10. confirmed N-terminal acetylation on all isoforms plus a single internal acetylation site; phosphorylation sites were located on peptides containing the cyclin dependent kinase (CDK) consensus motif PMID: 15595731
    11. The binding of histone H1 to a general amyloid-like motif indicates that histone H1 may play an important common role in diseases associated with amyloid-like fibrils. PMID: 16854430
    12. Histone H1.2 was translocated from the nucleus to the mitochondria after treatment with bleomycin and co-localized with Bak in mitochondria. PMID: 17879944
    13. that the recruitment of YB1, PURalpha, and H1.2 to the p53 target gene Bax is required for repression of p53-induced transcription. PMID: 18258596
