Anti-IL-28 Antibody

A rabbit-derived polyclonal reagent from Antibodies.com that recognizes human interleukin-28 (IL-28, also called interferon lambda 3, IFN-λ3), a type III interferon cytokine implicated in mucosal antiviral defense and epithelial barrier function. The antibody is unconjugated and supplied as 100 µl of liquid for direct use in Western blot and ELISA workflows.

The polyclonal format generates recognition of multiple epitopes across the IL-28 protein, which helps when detecting endogenously expressed cytokine in primary human samples or lysates prepared from epithelial and immune cell sources. The reagent was raised in Rabbit and validated for human reactivity, supporting studies of cytokine induction, viral challenge responses, and signaling pathway mapping related to the IL-28Rα/IL-10Rβ receptor complex.

Working concentrations should be titrated empirically for each application, with optimization of sample dilution and incubation time depending on the assay format. Store refrigerated for short-term use, or aliquot and freeze for longer term storage, avoiding repeated freeze-thaw cycles of the vial.
