    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.

  • 蛋白标签：
    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.
  • Datasheet ：

  • 基因功能参考文献：
    1. rs12077871, rs12722877, and rs7533552 variants in COL9A2 were not significantly associated with a predisposition to lumbar disc degeneration. PMID: 29506578
    2. Study provides evidence that the COL9A2 Gln326Arg polymorphism contributes to the development of intervertebral disc disease in the Chinese population. PMID: 28002589
    3. Meta-analysis. Our results suggest that the COL9A2 rs12077871, rs12722877, and rs7533552 polymorphisms may not be associated with lumbar disc disease. PMID: 24983932
    4. Two novel mutations, c.143G>C in exon 2 and c.884G>A in exon 17 of the COL9A2 gene, may contribute to the development of pathological myopia. PMID: 24711017
    5. The allelic variants in the collagen IX genes - COL9A2 and COL9A3 have been identified as genetic risk factors for intervertebral disc disease--{review} PMID: 24636772
    6. Studies indicate that two SNPs that introduce tryptophan polymorphisms in COL9A2 and COL9A3 are independently linked to an increased risk of lumbar disc disease. PMID: 21311409
    7. Data indicate that no causal SNPs in COL9A2 were significantly associated with LSS, but Haplotype Analysis showed that the "GCAGCG" haplotype (HAP2) was overrepresented in LSS patients. PMID: 21228751
    8. loss of function mutation in the COL9A2 gene causes autosomal recessive Stickler syndrome PMID: 21671392
    9. Data show that the associating G allele in COL9A2 changes a glutamine to arginine or to tryptophan and may predispose to both hip osteoarthritis and lumbar disc degeneration, making it a candidate for degenerative connective tissue diseases. PMID: 21159828
    10. mutations leading to skipping of exon 3 within the COL3 domain of the alpha2-chain of collagen type IX may be relatively common in patients with a special subtype of multiple epiphyseal dysplasia PMID: 12244547
    11. Both Trp2 and Trp3 allelic products are incorporated into cross-linked fibrillar network of developing human cartilage apparently normally. Any pathological consequences are likely to be long-term and indirect rather than from overt misassembly of matrix. PMID: 12782139
    12. The collagen IX is cartilage specific, and expressed in hypertrophic chondrocytes and bone. PMID: 15625128
    13. A population study using magnetic resonance imaging to define degenerative disc disease demonstrates that the TRP2 allele (Gln326Trp)of COL9A2 is a significant risk factor for development and severity of degeneration. PMID: 16371896
    14. A Japanese family with an autosomal dominant multiple epiphyseal dysplasia (MED EDM2) was studied; genomic analysis for COL9A2 identified an Ex3-1A>G heterozygous mutation, which has been proved to result in skipping of exon 3. PMID: 16440132
    15. Association of a COL9A2 specific haplotype with lumbar disc disease in the Japanese population. PMID: 17024315
    16. Homozygosity for the Arg allele of Col9A2 seems to be more frequent in the patient group with early recurrence although the differences in the allele frequencies were statistically not significant. PMID: 18080148
    17. COL9A2 polymorphisms were associated with intervertebral disc mechanics, relating genetic variations and debilitating mechanical alterations that may ultimately result in intervertebral disc degeneration. PMID: 18246003
