Rat IL-13/Interleukin-13 ELISA Kit PicoKine®

Interleukin 13 (IL-13) is a protein that in humans is encoded by the IL13 gene. IL-13 is cytokine secreted by many cell types, but especially T helper type 2 (Th2) cells, 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-4Ralpha) and at least one of two known IL-13-specific binding chains. Most of the biological effects of IL-13, like those of IL-4, are linked to a single transcription factor, signal transducer and activator of transcription 6 (STAT6) . The IL13 gene is clustered with IL3, IL5, IL4, and CSF2 on 5q. Physical maps of the 5q23-q31 region show the following order: cen--IL3--CSF2--IL13--IL4--IL5--tel, with IL13 particularly close to IL4.
