    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：
    C1r B chain is a serine protease that combines with C1q and C1s to form C1, the first component of the classical pathway of the complement system.
  • 基因功能参考文献：
    1. The serine protease domains of C1r and C1s are at the periphery of the C1r2s2 tetramer both when alone or within the nonactivated C1 complex. The C1 complex adopts a conformation incompatible with intramolecular activation of C1. Instead, intermolecular proteolytic activation between neighboring C1 complexes bound to a complement-activating surface occurs. Many structurally unrelated molecular patterns can activate C1. PMID: 28104818
    2. We identified a novel, homozygous, loss-of-function mutation (p.Pro445Leufs*11) in the C1R gene. Using the Sanger method of DNA sequencing in 14 family members, we confirmed the presence of the mutation in 4 patients with early-onset systemic lupus erythematosus and in an asymptomatic 9-year-old girl. Complement levels were low in sera from patients with truncated C1r protein. PMID: 28544690
    3. Periodontal Ehlers-Danlos Syndrome in at least the great majority of cases results from specific classes of heterozygous mutations in C1R and C1S. PMID: 27745832
    4. We confirmed increased levels of C1R and VTN in sera from patients with Joint hypermobility syndrome by western blot analyses PMID: 26709396
    5. C1q exists as the C1 complex (C1qC1r2C1s2), and C1q binding to ligands activates the C1r/C1s proteases. Incubation of nucleoli with C1 caused degradation of the nucleolar proteins nucleolin and nucleophosmin 1. T PMID: 26231209
    6. C1r specificity is well suited to its cleavage targets and that efficient cleavage of C1s is achieved through both active site and exosite contributions. PMID: 23589288
    7. a structural rearrangement as a switch between functional states of human C1r PMID: 20970424
    8. These results provide further structural insights into the architecture of the C1 complex, and the interactions between C1r and C1s. PMID: 20592021
    9. The modular C1r protein is the first protease activated in the classical complement pathway, a key component of innate immunity. PMID: 20796027
    10. Detailed mapping of C1q post-translational modifications and insights into the C1r/C1s binding sites. PMID: 20008834
    11. Using a recombinant CUB2-CCP1 domain pair and the individual CCP1 module, we showed that binding of Ca(2+) induces the folding of the CUB2 domain and stabilizes its structure. PMID: 20178990
    12. These findings show no evidence for association between C1r codon 135 polymorphism and Alzheimer's Disease in our population. PMID: 12499050
    13. Six common and rare alleles, C1R*1, C1R*2, C1R*5, C1R*8, C1R*9, and C1R*13, were characterized by five mutations at amino acid positions 114, 135, 146, 167 and 244, in exons 4, 5 and 7 where the PMID: 12914573
    14. The activated CCP1-CCP2-SP fragment makes up a dimer in a head-to-tail fashion similarly to the previously characterized zymogen. PMID: 17996945
    15. The catalytic properties of C1r, the protease that mediates activation of the C1 complex of complement, are mediated by its C-terminal region, comprising two complement control protein (CCP) modules followed by a serine protease (SP) domain PMID: 11445589
