| Description | IL31 mouse recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 141 amino acids and having a molecular mass of 15.7 kDa. |
| Expression host | Escherichia Coli. |
| Formulation | The IL31 (1mg/ml) was lyophilized from 10mM sodium Phosphate pH-7.4. |
| Physical Appearence | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Protein Background | IL-31 produced by activated Th2-type T cells, cooperates with a heterodimeric receptor consisting of IL-31 Receptor Anatagonist and Onconstatin-M Receptor that is continuesly expressed on epithelial cells and keratinocytes. IL-31 plays a role in the promotion of allergic skin disorders and in regulating other allergic diseases, such as asthma. IL-31 is involved in the itching sensation and endorses the scratching behavior in NC/Nga mice with atopic dermatitis. IL-31 expression is connectd with CLA(+) T cells and contributes to the development of atopic dermatitis-induced skin inflammation and pruritus. IL-31 is a powerful inducer of proinflammatory mediators in human colonic SEMFs. IL-31 takes part as a proinflammatory cytokine derived from Th2 cells.Serum IL-31 level is higher in patients with atopic dermatitis. IL-31 is involved in a broad range of immune- & non-immune cells & possesses potential pleiotropic physiological functions, including regulating hematopoiesis & immune re |
| Purity | Greater than 97.0% as determined by(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE. |
| Solubility | It is recommended to reconstitute the lyophilized IL31 in sterile 18M?-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized IL31 Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL31 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles. |
| Synonyms | Interleukin 31, IL31, IL-31. |
