    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.

    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.

    7. Short-term treatment with progressive doses of rhIGF1 (recombinant human insulin-like growth factor-1) improved growth in two siblings with deficiency of PAPP-A2 (pregnancy-associated plasma protein-A2) [due to a homozygous loss-of-function frameshift mutation in exon 3 of the PAPP-A2 gene (p.D643fs25*)] that resulted in postnatal growth failure due to resulting decrease in IGF1 bioavailability. [CASE REPORT] PMID: 27648969
    8. in situ hybridization (ISH) and immunohistochemistry (IHC) were employed to examine the spatial and temporal expression of PAPPA2 in the human fetomaternal interface. PMID: 27525857

    11. The association between this PAPPA2 single nucleotide polymorphism and developmental dysplasia of the hip was evaluated. PMID: 24672801
    12. The upregulation of PAPP-A2 observed in preeclampsia at term occurs early in pregnancy, before the symptoms develop. PMID: 24336677
    13. PAPPA2 may be upregulated in severe pre-eclampsia and, functionally, this may be mediated via increased placental hypoxia known to occur with this pregnancy disorder. PMID: 23484525

    17. Circulating IGFBP-5 is proteolyzed by PAPP-A2 during pregnancy, resulting in increased IGF bioavailability, which may have important consequences for the development of the fetus and/or the well-being of the mother. PMID: 20103653
    18. Seven placental transcripts characterize HELLP-syndrome. PMID: 18374411
    19. PAPP-A2 in syncytiotrophoblast cells was dramatically increased in pre-eclampsia. Maternal serum concentrations of PAPP-A2 were also significantly elevated in pre-eclampsia as compared with uncomplicated pregnancy. PMID: 18805800
