Rat Interleukin 13 ELISA kit

靶标信息

Human IL13 was originally identified by differential screening of an anti CD28 activated human peripheral blood mononuclear cell cDNA library as an induction specific novel cytokine. It was also isolated from cDNA libraries of human T cell clones using the murine IL13 (P600) cDNA as a probe. Human IL13, a pleiotropic cytokine, is produced by activated Th0, Th1 like, Th2 like, and CD8 T cells. The gene for human IL13 maps to chromosome 5 and is closely linked to the genes for IL3, IL4, IL5, and GMCSF.IL13 inhibits proinflammatory cytokine production and stimulates antibody production. It induces proliferation in the human pre myeloid cell line TF1. IL13 has multiple effects on the differentiation and functions of monocytes and macrophages. It suppresses cytotoxic functions and induces changes in the morphology of human monocytes and in the phenotype of human monocytes and B cells by upregulating MHC class II expression. IL13 will also decrease the production of nitric oxide by activated murine macrophages, leading to impaired parasiticidal activity.Human and mouse interleukin 13 share approximately 58% amino acid sequence identity. Although human and mouse IL13 are equally active on human cells, human IL13 is much less active than mouse IL13 on mouse cells. Human IL13 and human IL4 also share approximately 30% sequence homology and have similar biological functions.
