Beskrivning

AA Sequence of recombinant protein: TPGPVRRSTS PPVALRELIE ELSNITQDQK TSLCNSSMVW SVDLTAGGFC AALESLTNIS SCNAIHRTQR ILNGLCNQKA SDVASSPPDT KIEVAQFISK LLNYSKQLFR YGH. Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Rat IL-13. Anti-Rat IL-13-specific antibody was purified by affinity chromatography and then biotinylated. Sandwich ELISA: To detect Rat IL-13 by sandwich ELISA (using 100 mL/well) a concentration of 0.25-1.0 μg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti- Rat IL-13 (500-P224) as a capture antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Rat IL-13. Western Blot: To detect Rat IL-13 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 mg/mL. When used in conjunction with compatible development reagents the detection limit for Recombinant Rat IL-13 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions. 500-P224BT-1MG will be provided as 2 x 500 μg

IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and is involved in regulating inflammatory and immune responses. IL-13 down-regulates macrophage activity, thereby inhibiting the production of pro-inflammatory cytokines and chemokines, and is involved in allergen-induced asthma through mechanisms independent of IgE and eosinophils. IL-13 also regulates several stages of B cell maturation and differentiation, up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. Structurally, IL-13 closely resembles IL-3, IL-4, IL-5 and GM-CSF. The gene encoding IL-13, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with the IL-13 gene particularly close to IL4.
