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
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.
Form
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
Reconstitution
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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Activates STAT3 and possibly STAT1 and STAT5 through the IL31 heterodimeric receptor composed of IL31RA and OSMR. May function in skin immunity. Enhances myeloid progenitor cell survival in vitro. Induces RETNLA and serum amyloid A protein expression in macrophages.

  3. IL-31 increased the concentration of intracellular Ca(2+) ions in mouse keratinocytes. PMID: 29477033
  4. IL-31 elicits itch not only through direct action on primary sensory neurones, but also by inducing LTB4 production in keratinocytes. PMID: 28512667
  5. IL31 and its receptor, IL31RA, are highly expressed in various human and mouse cancer cell lines, as well as in tumor specimens from cancer patients. MC38 murine colon carcinoma cells depleted of IL31 exhibit an increase in invasive and migratory properties in vitro. PMID: 28147314
  6. Oncostatin M and interleukin-31: Cytokines, receptors, signal transduction and physiology. PMID: 26198770
  7. IL-31 upregulates IL-31RA expression in DRG neuron cell bodies, and cutaneous-injected IL-31-induced itching is enhanced by DRG IL-31RA expression in mice PMID: 25381841
  8. our results suggest a functional cooperation between NFAT1 and JunB in mediating IL-31 gene expression in CD4(+) T cells PMID: 25595785
  9. Data not only illustrate various functions that cysteines perform during IL-31 biosynthesis and secretion, but also highlight their potential roles in cytokine effector functions. PMID: 21182835
  10. IL-31 may be involved in promoting the dermatitis and epithelial responses that characterize allergic and non-allergic diseases PMID: 15184896
  11. IL-31 interaction with IL-31 receptor (IL-31R) is identified in an acute model of T helper cell type 2 inflammation in the lung. PMID: 17353366
  12. -31 antibody reduces scratching behaviour in an atopic dermatitis-like murine model during the onset of clinical skin manifestations PMID: 19054054
  13. these data provide the first evidence of a function for IL-31-IL-31R interactions in limiting the magnitude of type 2 inflammatory responses within the intestine. PMID: 19414760
