Human IL-29 ELISA kit for the quantitative detection of human Interleukin-29 in cell culture supernates, serum and plasma (heparin, EDTA).

Interferon lambda-1, also called interleukin-29 (IL-29) is a protein that in humans is encoded by the IL29 gene. IL-29 is a member of the helical cytokine family and is a type III interferon. This gene is mapped to 19q13.2. It is a cytokine with immunomodulatory activity. This gene may play a role in antiviral immunity. It can up-regulates MHC class I antigen expression. It is the ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1. The ligand/receptor complex seems to signal through the Jak-STAT pathway. IL-29 plays an important role in host defenses against microbes and its gene is highly upregulated in cells infected with viruses.
