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. Recombinant protein corresponding to aa22-196 from human Interferon lambda 3, fused to 6xHis-Tag at C-terminal, expressed in Mammalian cells. Molecular Weight: ~20.67kD Biological Activity: The ED50 as determined by its ability to binding IL10RB used funtional ELISA is less than 10ug/ml.
