Human IL-29 (Interleukin 29) ELISA Kit

The kit is a Sandwich enzyme immunoassay for in vitro quantitative measurement of IL-29 in serum, plasma and other biological fluids. Detection Range: 15.63--1000pg/mL. Sensitivity: 9.38pg/mL. Protein function: Cytokine with antiviral, antitumour and immunomodulatory activities. Plays a critical role in the antiviral host defense, predominantly in the epithelial tissues. Acts as a ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1, and receptor engagement leads to the activation of the JAK/STAT signaling pathway resulting in the expression of IFN- stimulated genes (ISG), which mediate the antiviral state. Has a restricted receptor distribution and therefore restricted targets: is primarily active in epithelial cells and this cell type- selective action is because of the epithelial cell-specific expression of its receptor IFNLR1. Exerts an immunomodulatory effect by up-regulating MHC class I antigen expression. [The UniProt Consortium]
