Interleukin-29 (IL-29, IFN-λ1) is a member of the type III interferon family of cytokines. It shares a high degree (~80%) of amino acid sequence homology with both IL-28A (IFN-λ2) and IL-28B (IFN-λ3). IL-29 is produced by human peripheral blood mononuclear and dendritic cells in response to viral infection, TLR stimulation, or other type I IFN agonists. IL-29 has been demonstrated to upregulate MHC I expression on target cells; in addition, IL-29 also mediates the antiviral immune response to several viruses including Hepatitis B (HBV), Hepatitis C (HCV), and Human Immunodeficiency Virus (HIV). Increased serum levels of IL-29 have also been reported in Hashimoto’s thyroiditis patients.

The BioLegend LEGEND MAX™ Human IL-29 (IFN-λ1) ELISA Kit is a Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) with a 96-well strip plate that is pre-coated with a polyclonal goat anti-human IL-29 capture antibody. The detection antibody is a biotinylated polyclonal goat anti-human IL-29 antibody. This kit is specifically designed for the accurate quantitation of human IL-29 (IFN-λ1) from cell culture supernatant, serum, plasma, and other biological fluids. This kit is analytically validated with ready-to-use reagents.

Related FAQs

For some of your ELISA kits, why do my serum samples require dilution with assay buffer?

Dilution with assay buffer is required to minimize the matrix difference between the samples and the standards to achieve better accuracy.

I have multiple LEGEND MAX™ ELISA kits that I want to run simultaneously. Can I use the same wash buffer for all the kits?

The Wash buffer is the same for all the current LEGEND MAX™ kits. All the part numbers on the Wash Buffer bottles in these kits should be the same. For ELISA MAX™ Deluxe and ELISA MAX™ Standard sets, we provide a recipe for the wash buffer on each kit’s technical data sheet. This recipe is the same for all ELISA MAX™ sets.

In your LEGEND MAX™ ELISA Kits, there is a step that calls for a washing of the plates before even adding any sample to it. What is the purpose of this step?

We typically use a stabilizer for pre-coated plates. The washings were designed to remove these components before you start the assay. If you do not do the washings, the effect on assay performance is negligible.
