    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.

  • 基因功能参考文献：
    1. In the process of assay optimization, we discovered that PHPT1 is sensitive to a reducing environment and inhibited by transition-metal ions, with one apparent Cu(II) binding site with IC50 value of 500 +/- 20 muM and two apparent Zn(II) binding sites with IC50 values of 25 +/- 1 and 490 +/- 20 muM PMID: 29630837
    2. High PHPT1 expression is associated with cancer. PMID: 29787434
    3. H2O2 exposure induces selective oxidation of hPHPT1 at Met95, a residue within the substrate binding region. Molecular dynamics simulations suggest that if Met95 oxidation alters hPHPT1 activity, then it will do so by altering the stability of an intermediate state. Mass spectrometry showed that H2O2-induced oxidation does not impact hPHPT1 function negatively. PMID: 27034094
    4. PHPT1 was expressed in the epithelium of proximal tubuli and nuclei of clear-cell renal cell carcinoma tissue samples. PMID: 26537769
    5. PHPT1 can dephosphorylate phospholysine in chemically phosphorylated histone H1 and polylysine PMID: 25574816
    6. The specific degradation of the PHPT1 splice variant indicates that the quality control and the self-guarding of the cellular system works at two levels, first at the RNA level and proteasome level. PMID: 25450458
    7. the histidine phosphatase, protein histidine phosphatase 1, inhibits NDPK-B-activated TRPV5 in inside/out patch experiments. PMID: 24523290
    8. Overexpression of PHP by the use of a plasmid vector, pIRES2-AcGFP1-PHP, induced apoptosis in HUVEC PMID: 21967643
    9. Significantly higher expression levels of PHPT1 protein were found in lung cancer samples than in normal tissues adjacent to lung cancer. PMID: 21163124
    10. these data implicate regulatory roles for PHPT1 in a G protein-sensitive step involved in nutrient-induced insulin secretion PMID: 20501872
    11. These results demonstrate for the first time that PHP14 may be functionally important in lung cancer cell migration and the invasion of lung cancer cells, mediated partly through modulation of actin cytoskeleton rearrangement. PMID: 19344975
    12. Northern blot analysis indicated that the human phosphohistidine phosphatase mRNA was present preferentially in heart and skeletal muscle. PMID: 12383260
    13. In the present work, we have searched for potential active site residues in the human phosphohistidine phosphatase by point mutations of conserved histidine and arginine residues to alanine. PMID: 16219293
    14. Overexpression of PHP results in increased dephosphorylation with concomitant inactivation of ACL, thus finally leading to cell damage. PMID: 18656514

    16. Solution structure and catalytic mechanism of human protein histidine phosphatase 1. PMID: 18991813
