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.
Troubleshooting 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

Acts as component of the MCM2-7 complex (MCM complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the MCM2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differentially to the complex helicase activity. Required for DNA replication and cell proliferation.

  3. reveal the Minichromosome Maintenance Complex to be a critical and directly regulated node within the miR-183 signaling network in MYCN-amplified neuroblastoma cells. Randomly selected MCMs 3 and 5 were experimentally confirmed as direct targets of miR-183. PMID: 27239679
  4. The results of our preliminary study emphasize the need for future research on MCM-3 as a sensitive proliferation marker, providing an alternative to Ki-67, in cases of various major salivary gland epithelial tumors in children and adolescents. PMID: 28547962
  5. These data establish new functions for KEAP1 within the nucleus and identify MCM3 as a novel substrate of the KEAP1-CUL3-RBX1 E3 ligase. PMID: 27621311
  6. The aim of this study is to analyze the immunoexpression of Ki67, p53, MCM3 and PCNA markers in epithelial remnants of dental follicles of impacted teeth and to identify a possible correlation between the immunoexpression of these markers in dentigerous cysts and keratocystic odontogenic tumors. PMID: 27516012
  7. High MCM-3 expression correlated with Cutaneous T-cell Lymphomas. PMID: 26504025
  8. normal DNA replication and replication checkpoint activation is regulated through the novel phosphorylation of MCM3 by Chk1 PMID: 25809478
  9. The relatively lower MCM3 protein expression in FVPTC. PMID: 23821456
  10. Expression of KB cell MCM3 was not affected by doxorubicin. PMID: 24344040
  11. present study aimed to investigate the relationship between expression of minichromosome maintenance proteins (MCM-3, MCM-7), metallothioneins (MT-I/II, MT-III), and Ki-67 in 103 ovarian cancer cases, mostly of the serous histological type PMID: 24324072
  12. High MCM3 expression is associated with mucoepidermoid carcinomas and adenoid cystic carcinomas in salivary gland tumors. PMID: 23886132
  13. Relatively lower MCM3 protein expression in follicular variant of papillary thyroid carcinoma comparing to classical type could be due to a different tumorigenic pathway favored in this type of tissue. PMID: 23821456
  14. These findings provide validation of the utility of MCM3 expression as an independent biomarker for prognostication of patients with primary melanoma PMID: 22805320
  15. excess of MCM3 up-regulates the phosphorylation of CHK1 Ser-345 and CDK2 Thr-14. PMID: 21965652
  16. MCM3 gene expression is decreased in follicular variant of papillary thyroid carcinoma, contrary to expectation. PMID: 21509594
  17. Using U373MG cells we found that HCMV IE86 protein was bound to Mcm3, but did not inhibit the cellular DNA synthesis. PMID: 20545442
  18. MCM3 may be a more reliable proliferation marker than Ki-67 in accessing the growth of tumor and evaluating tumor aggressiveness of papillary thyroid carcinoma. PMID: 19818763
  19. The MCM3 acetylase MCM3AP inhibits initiation, but not elongation, of DNA replication via interaction with this protein PMID: 12226073
