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.
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
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.
and FAQs
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Integrin alpha-7/beta-1 is the primary laminin receptor on skeletal myoblasts and adult myofibers. During myogenic differentiation, it may induce changes in the shape and mobility of myoblasts, and facilitate their localization at laminin-rich sites of secondary fiber formation. It is involved in the maintenance of the myofibers cytoarchitecture as well as for their anchorage, viability and functional integrity. Isoform Alpha-7X2B and isoform Alpha-7X1B promote myoblast migration on laminin 1 and laminin 2/4, but isoform Alpha-7X1B is less active on laminin 1 (In vitro). Acts as Schwann cell receptor for laminin-2. Acts as a receptor of COMP and mediates its effect on vascular smooth muscle cells (VSMCs) maturation. Required to promote contractile phenotype acquisition in differentiated airway smooth muscle (ASM) cells.

  1. Speculate that the postnatal splicing of alpha7A to alpha7B and of beta1A to beta1D integrins is delayed, altering spontaneous descent of the testes in the first months of life. PMID: 30089289
  2. As knockdown of Integrin alpha7 (ITGA7) can effectively reduce the stemness of oesophageal squamous cell carcinoma (OSCC) cells, ITGA7 could be a potential therapeutic target in OSCC treatment. PMID: 27924820
  3. targeting of ITGA7 by RNAi or blocking mAbs impaired laminin-induced signaling, and it led to a significant delay in tumor engraftment plus a strong reduction in tumor size and invasion. PMID: 28602620
  4. Taken together, these results further support the use of a7 integrin as a potential therapy for Duchenne muscular dystrophy PMID: 26076707
  5. Data indicate that S100 calcium binding protein P (S100P) increased lung cancer cell migration by binding integrin alpha7. PMID: 26320193
  6. Data suggest that ITGA7 is an epigenetically regulated tumour suppressor gene and a prognostic factor in human malignant pleural mesothelioma. PMID: 26011651
  7. ITGA7 binds to tissue inhibitor of metalloproteinase 3 (TIMP3) in prostate cancer cells. PMID: 23830872
  8. The absence of either alpha7beta1 integrin or alpha6beta1 integrin impairs the ability of Schwann cells to spread and to bind laminin. PMID: 24227711

  10. Alpha7beta1D integrin modifies Ca2+ regulatory pathways and offers a means to protect the myocardium from ischemic injury. PMID: 24091324
  11. This report provides a novel insight into the mechanism, involving interaction with high temperature requirement A2, by which ITGA7 acts as a tumor suppressor. PMID: 20651226
  12. ILK interaction with MCM7 and MCM7 phosphorylation may be a critical event in ITGA7 signaling pathway, leading to tumor suppression. PMID: 20460506
  13. conclude that secondary integrin alpha 7 deficiency is rather common in muscular dystrophy/myopathy of unknown etiology PMID: 12057917
  14. FHL2 and FHL3, respectively, are colocalized with alpha(7)beta(1) integrin receptor at the periphery of Z-discs, suggesting a role in mechanical stabilization of muscle cells PMID: 15117962
  15. alpha7-expressing fetal myoblasts are capable of differentiation to osteoblast lineage with a coordinated switch in integrin profiles and may represent a mechanism that promotes homing and recruitment of myogenic stem cells for tissue remodeling. PMID: 17054947
  16. Integrin alpha7 mutations are associated with prostate cancer, liver cancer, glioblastoma multiforme, and leiomyosarcoma PMID: 17551147
  17. analysis of how distinct acidic clusters and hydrophobic residues in the alternative splice domains X1 and X2 of alpha7 integrins define specificity for laminin isoforms PMID: 17618648
  18. Alpha7B is a novel marker of the contractile phenotype, and alpha7 expression is essential for human airway smooth muscle cell maturation, which is a laminin-dependent process. PMID: 17641293
  19. cleavage is a novel mechanism that regulates alpha7 integrin functions in skeletal muscle, and that the generation of such cleavage sites is another evolutionary mechanism for expanding and modifying protein functions. PMID: 18940796
