    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.

    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：
    Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. Responsible for the transport of iron from sites of absorption and heme degradation to those of storage and utilization. There are two forms of hen transferrin, ovotransferrin, found in the ovoducts and, serum transferrin, secreted by the liver. Serum transferrin may also have a role in stimulating cell proliferation and is regulated by iron levels. Ovotransferrin has a bacteriostatic function and, is not controlled by iron levels.

    1. unfolding pathway and conformational stability of conalbumin PMID: 21833676
    2. glycosylation of fetal & hen ovotransferrin differs; hypothesized to alter ovotransferrin recognition by carbohydrate binding lectins PMID: 7881176
    3. studied the carbohydrate and amino acid compositions of the ovotransferrin glycopeptides PMID: 574451
    4. The exon structure of the ovotransferrin gene confirms the duplication event to produce two homologous domains that make up ovotransferrin PMID: 3658709
    5. evidence suggests that conalbumin (ovotransferrin) and transferrin are products of the same gene, differing only in carbohydrate content PMID: 4907959
    6. show both lobes are required for efficient iron binding and calculate binding kinetics. PMID: 6319414
    7. ovotransferrin folds into two compact, iron-binding domains; the authors demonstrate that the duplicated domain structure is necessary to retain ovotransferrin in plasma and stop immediate loss via kidney filtration PMID: 6805466
    8. The structure of ovotransferrin shows that the iron-binding site is located in the interdomain cleft in each lobe; differences in ovotransferrin structure cause changes to iron binding & uptake/release compared to lactotransferrin & transferrin. PMID: 7490743
    9. At a pH where the protein net charge is negative (pH 8.0), the behavior of ovotransferrin at the air-water interface is more influenced by charge effects rather than bulk concentration effects. PMID: 21316692
    10. Trp-Asn-Ile-Pro and Gly-Trp-Asn-Ile peptides of ovotransferrin showed the highest antioxidant activity. PMID: 20568771
    11. Marked stabilization effects by amino(N)- and carboxyl(C)-terminal lobes of ovotransferrin are induced during iron binding, primarily upon N-lobe iron binding in the iron-free C-lobe and secondarily upon C-lobe iron binding in the monoferric N-lobe. PMID: 15323571
    12. Ovotransferrin is able to cleave itself through the unique chemical reactivity of four tripeptides motifs, HTT (residues 209-211), HST (residues 542-544) and two CHT (residues 115-117 and 454-456). PMID: 16442235
    13. Several proteins associated with the egg shell membranes (ESM) with antibacterial activity have been identified including ovotransferrin, in addition, pure fractions of ovotransferrin were obtained from egg white. PMID: 16721662
