Conjugate 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 Info The following tags are available.
N-terminal His-tagged
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.
Form 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.
Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution 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.

Storage Condition Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life 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.
Lead Time 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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Inactive tyrosine kinase involved in Wnt signaling pathway. Component of both the non-canonical (also known as the Wnt/planar cell polarity signaling) and the canonical Wnt signaling pathway. Functions in cell adhesion, cell migration, cell polarity, proliferation, actin cytoskeleton reorganization and apoptosis. Has a role in embryogenesis, epithelial tissue organization and angiogenesis.
Gene References into Functions
  1. PTK7 regulates extracellular matrix integrity and the activity levels of RAC1 and myosin II, which in turn regulates Wolffian duct morphogenesis and therefore, epididymal function. PMID: 29580943
  2. In a Ptk7-deficient mouse strain, loss of Ptk7 leads to a diminished pool of hematopoietic stem cells but does not affect in vitro or in vivo differentiation. This is correlated with increased quiescence and reduced homing abilities of Ptk7-deficient hematopoietic stem and progenitor cells. PMID: 27183644
  3. Data suggest that protein tyrosine kinase 7 (PTK7) is essential for Wolffian duct morphogenesis and male fertility. PMID: 26944093
  4. data demonstrates that PTK7 regulates the activity of KDR biphasically by inducing oligomerization of KDR molecules at lower concentrations and by surrounding KDR molecules at higher concentrations. PMID: 25986862
  5. PTK7 expression plays an important role in the invasiveness of intrahepatic cholangiocarcinoma cells. PMID: 24587299
  6. Planar polarity of neural cell motility and intercalation requires Ptk7 function. PMID: 24703875
  7. acts in conjunction with the noncanonical Wnt pathway to orient epithelial planar cell polarity through modulation of myosin II-based contractile tension between supporting cells and hair cells PMID: 22560610
  8. The tyrosine kinase receptor, PTK7, is implicated in beta-catenin-dependent developmental processes. PMID: 21415598
  9. These findings illustrate a novel and pivotal role for Cdx function upstream of Ptk7 and neural tube closure in vertebrates. PMID: 21350009
  10. Chuzhoi mutation, that causes multiple abnormalities maps, to Chromosome 17 and carries a splice site mutation in Ptk7 and causes disruption of Ptk7 protein expression. PMID: 20704721
  11. Ptk7 mRNA was expressed at high levels in lung and un-pregnant uterus among adult tissues, and in the tail, limbs, somites, gut, and craniofacial regions among embryonic tissues, and suggest that PTK7 plays multiple roles in embryonic development. PMID: 15019986
  12. a mutation disrupts neural tube closure and stereociliary bundle orientation, and shows genetic interactions with a mutation in the mouse Van Gogh homologue vangl2 PMID: 15229603
  13. polarized cell behaviors underlying CE in the mouse, clearly define specific roles for planar polarity and for the novel planar cell polarity gene, Ptk7, as essential regulators of mediolateral cell intercalation during mammalian CE. PMID: 19439496
