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.

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
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 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 Data

Function Required in cooperation with CD79B for initiation of the signal transduction cascade activated by binding of antigen to the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Also required for BCR surface expression and for efficient differentiation of pro- and pre-B-cells. Stimulates SYK autophosphorylation and activation. Binds to BLNK, bringing BLNK into proximity with SYK and allowing SYK to phosphorylate BLNK. Also interacts with and increases activity of some Src-family tyrosine kinases. Represses BCR signaling during development of immature B-cells.
Gene References into Functions
  1. The incidence of MYD88 and CD79B mutations in patients with CD5(+) DLBCL is lower than that in patients with DLBCL-SS, suggesting that CD5(+) DLBCL is not the same disease as DLBCL-SS in terms of gene mutation status. PMID: 27915469
  2. Phosphorylation of CD79a causes a decrease in helical propensity in the C-terminal region, for CD79b, the opposite was observed and phosphorylation resulted in an increase of helical propensity in the C-terminal part. PMID: 24769851
  3. High intensity of caries is associated with increased levels of some salivary components - sIgA, histatin-5 and lactoperoxidase. PMID: 24974109
  4. CD79a plays a functional role in the tumor promoting effects of myeloid cells, and may represent a novel target for cancer therapy. PMID: 24146823
  5. STN produced significant antitumor effects in a mouse xenograft model of CD79A/B-mutated DLBCL. PMID: 21324920
  6. CD79a may be helpful marker in the differential diagnosis of classical Hodgkin's lymphoma and primary mediastinal B-cell lymphoma PMID: 20102401
  7. Unlike the B29 octamer motif, the mb-1 octamer motif does not have the essential sequence required for OBF-1/Bob1 interaction, therefore its promoter is not transactivated by OBF-1/Bob1. PMID: 11907094
  8. B cell-restricted mb-1 gene: expression, function, and lineage infidelity. Review. PMID: 12403343
  9. There is a somatic hypermutation of this gene in B-cell lymphoma and multiple myeloma. PMID: 12651942
  10. Results indicate that PAX5 is a more specific marker than CD79a for B-cell ALL diagnosis. PMID: 15492262
  11. lower levels of B-cell receptor surface expression observed in chronic lymphocytic leukemia are accounted for by an impaired glycosylation and folding of the mu and CD79a chains. PMID: 15591116
  12. FISH findings indicate that CD79a, despite its specificity for B-cell differentiation, represented the aberrant presence of a B-cell antigen in leukemias of distinct myeloid linage. PMID: 16271957
  13. Acute leukemia with t(8;21) coexpresses CytCD79a represent biphenotypic acute leukemia. PMID: 17350472
  14. Anti-CD79b antibodies downregulated surface B-cell receptor and were trafficked to the lysosomal-like major histocompatibility complex class II-positive compartment of a mouse xenograft model of non-Hodgkin lymphoma. PMID: 17374736
  15. Ig-alpha was phosphorylated in all myeloma IgG BCR isolates, the 31-kD variant being phosphorylated most frequently. It was not phosphorylated in normal control B cells. PMID: 17701175
  16. Median survival time of cytoplasmic CD79 alpha positive group was shorter than that of cytCD79a negative group in acute myeloid leukemia. PMID: 18160827
