Abbreviation: IL-29
Target Synonym: Interferon lambda-1;IFN-lambda-1;ytokine Zcyto21;Interleukin-29;IL29;IFNL1;ZCYTO21
Target Species: Human
Expression Host: HEK293 Cells
Fusion Tag: N-10His
UNIProt ID: Q8IU54
Background: 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.
Sequence: Met1-Thr200
Purity: > 95 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4., 5% trehalose, 5% mannitol, 0.01% tween-80.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Endotoxin: < 1.0 EU per ug of the protein as determined by the LAL method.
