  • 产品提供形式:
    Liquid or 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.
  • 缓冲液:
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
  • 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.
  • 注意事项:
    Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

  • 功能:
    Acts as a negative regulator of the Toll-like and IL-1R receptor signaling pathways. Attenuates the recruitment of receptor-proximal signaling components to the TLR4 receptor, probably through an TIR-TIR domain interaction with TLR4. Through its extracellular domain interferes with the heterodimerization of Il1R1 and IL1RAP.

    10. An association was found in the SIGIRR rs7396562 polymorphism and systemic lupus erythematosus susceptibility in a Chinese population. PMID: 24826913
    11. IL-37 requires the receptors IL-18Ralpha and IL-1R8 to carry out its multifaceted anti-inflammatory program upon innate signal transduction. PMID: 25729923
    12. IL-37 acts as an extracellular cytokine by binding to the IL-18 receptor but using the IL-1R8 for its anti-inflammatory properties. PMID: 25654981
    13. Lipopolysaccharide decreases SIGIRR expression by suppressing specificity protein 1 Sp1 via the TLR4-p38 pathway in monocytes and neutrophils. PMID: 24821721

    15. These results demonstrate a strong association of single-nucleotide polymorphisms in the PKP3-SIGIRR-TMEM16J gene region and tuberculosis in discovery and validation cohorts. PMID: 22223854
    16. These results suggest that PALM3 may function as an adaptor in the LPS- Toll-like receptor 4 signaling and the interaction of SIGIRR with PALM3 may partly account for the mechanism of the negatively regulatory effect of SIGIRR. PMID: 21187075
    17. SIGIRR is expressed constitutively in intestinal epithelial cells to maintain gut innate immunity and then down-regulated during inflammation by inhibition of an SP1-mediated pathway. PMID: 21077278
