Antibody DetailsProduct DetailsReactivity Species Mouse Host Species Rat Immunogen Purified Recombinant Mouse IL-13 (>98%) Endotoxin Level <0.1 EU/µg as determined by the LAL method Formulation This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.4 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present. Storage and Handling The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months. Country of Origin USA Shipping Next Day Ambient RRIDAB_2830786 Applications and Recommended Usage? Quality Tested by Leinco ELISA Sandwich: This antibody is useful as the capture antibody in a sandwich ELISA. The suggested coating concentration is 4 µg/ml. A suitable detection antibody is PN:I-349 at a concentration of approximately 0.1-0.4 µg/ml. When used in conjunction with an optimal second step reagent such as PN:A106 and a chromogenic substrate such as PN:T118, the sensitivity of this sandwich ELISA is 4 ng/well. A suggested standard for this assay is PN:I-278. Western Blotting: To detect Mouse IL-13 this monoclonal antibody can be used at a concentration of 1-2 µg/ml. This monoclonal antibody should be used in conjunction with compatible second-step reagents such as PN:R377 and a chromogenic substrate such as PN:T343. The detection limit for Mouse IL-13 is 25 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:I-278. Other Applications Reported In Literature ? Neutralization: This antibody is useful for neutralization of Mouse IL-13 bioactivity. The antibody dose required to neutralize 50% (ND50) of the biological activity of Mouse IL-13 (at 10 ng/ml) is 0.3 - 0.8 µg/ml. Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change. DescriptionSpecificity Rat Anti-Mouse Interleukin 13 (IL-13) (Clone 38213) recognizes an epitope on Mouse IL-13. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype. Background Interleukin 13 (IL-13) is a cytokine secreted by many cell types, but especially T helper type 2 (Th2) cells1, that is an important mediator of allergic inflammation and disease. IL-13 induces its effects through a multi-subunit receptor that includes the alpha chain of the IL-4 receptor (IL-4Rα), which is also a component of the IL-4 receptor, and at least one of two known IL-13-specific binding chains.1 The functions of IL-13 overlap considerably with those of IL-4. Although IL-13 is associated primarily with the induction of airway disease, it also has anti-inflammatory properties. IL-13 induces many features of allergic lung disease, including airway hyperresponsiveness, goblet cell metaplasia and mucus hypersecretion, which all contribute to airway obstruction.
