Description
| Product Name: | Human IL 13 Variant Recombinant Protein |
| Product Code: | RPPB0575 |
| Size: | 10µg |
| Species: | Human |
| Target: | IL 13 Variant |
| Synonyms: | Interleukin-13, NC30, ALRH, BHR1, P600, IL-13, MGC116786, MGC116788, MGC116789. |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | Lyophilized from a 0.2�m filtered concentrated solution in 1xPBS, pH 7.2, containing 5% trehalose. |
| Solubility: | It is recommended to reconstitute the lyophilized Interleukin 13 Variant in sterile 18M?-cm H2O not less than 100�g/ml, which can then be further diluted to other aqueous solutions. |
| Stability: | Lyophilized Interleukin-13 Variant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL13 Variant should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Purity: | Greater than 95% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |

| Biological Activity: | The ED50 was determined by the dose dependent prolifiration of TF-1 cells and was found to be < 1ng/ml, corresponding to a specific activity of >1,000,000 units/mg. This analog has also been shown to exhibit increased in vivo activity compared to wild type IL-13. |
IL13 is an immunoregulatory cytokine produced primarily by activated Th2 cells. IL-13 is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils. This gene, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL4.
Interleukin-13 Variant Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 114 amino acids, with a substitution of Q for R at position 112 compared with the wild type IL-13, having a molecular mass of 12.5 kDa. The IL-13 Variant is purified by proprietary chromatographic techniques.
| UniProt Protein Function: | IL13: Cytokine. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Defects in IL13 may be a cause of susceptibility to allergic rhinitis (ALRH). Allergic rhinitis is a common disease of complex inheritance and is characterized by mucosal inflammation caused by allergen exposure. Belongs to the IL-4/IL-13 family. |
