    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 ：

  • 功能：
    Possible role in modulating immune responses. Induces morphological changes including production of filopodia and microspikes when overexpressed in a variety of cell types and may be involved in dendritic cell maturation. Isoform 1 and isoform 2 have an inhibitory effect on lymphocyte proliferation.
  • 基因功能参考文献：
    1. Increased expression of LST1 in GC-responders before therapy warrants further investigation into their role as potential predictors for the response to GC, and in the inflammatory process of rheumatoid arthritis. PMID: 27384923
    2. Data indicate that the MHC class III gene LST1 5' untranslated regions (5'-UTR) contains several upstream open reading frames (uORFs). PMID: 24816991
    3. Psoriasis was associated with promoter variant, rs9267502 of LST1.Promoter activity was examined and it was larger than that of the other genetic variants, most probably due to changes in binding affinity to transcription factors. PMID: 24803336
    4. This is the first report demonstrating regulated LST1 expression in human intestinal epithelial and microvascular endothelial cells and in inflamed colonic tissue from IBD patients. PMID: 24682411
    5. induces the formation of functional nanotubes PMID: 23239025
    6. LST1 is expressed specifically in leukocytes of the myeloid lineage, where it localizes to the tetraspanin-enriched microdomains andit binds SHP-1 and SHP-2 phosphatases. PMID: 22589543
    7. Study found association between extended LTA, TNF, LST1 and HLA gene haplotypes and rubella vaccine-induced immunity. PMID: 20668555
    8. Human dendritic cells activate resting natural killer (NK) cells and are recognized via the NKp30 receptor by activated NK cells. PMID: 11828009
    9. Expression of this receptor, inhibited by TGF-beta1, affects NK-mediated killing of dendritic cells PMID: 12646700
    10. The expression of LST1, specifically splice variants encoding soluble isoforms and NCR3, was increased in rheumatoid-arthritis-affected blood and synovium and was associated with more severe inflammation in the synovium. PMID: 16362817
    11. LST1 protein expression in human cell lines was found to be tightly regulated, allowing the expression of transmembrane isoforms but suppressing soluble isoforms PMID: 19663701
