Interleukin-22 plays a pivotal role in mucosal immunity and tissue homeostasis, functioning as a key mediator between immune cells and epithelial barriers. Produced primarily by T helper subsets and innate lymphoid cells, IL-22 signals through its heterodimeric receptor to regulate antimicrobial defense, wound healing, and inflammatory responses in tissues including the gut, skin, and respiratory tract. Its involvement in both protective immunity and pathological inflammation makes IL-22 a compelling target for researchers investigating autoimmune conditions, infectious diseases, and tissue regeneration.
This recombinant monoclonal antibody against human IL-22, generated using clone 4E4, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant antibodies are produced from defined sequences rather than hybridoma supernatants, researchers benefit from lot-to-lot uniformity that supports longitudinal studies and multi-site collaborations. The human IgG1 isotype format and affinity-chromatography purification ensure high specificity with minimal background interference.
Validation studies demonstrate reliable performance in immunohistochemistry applications, with successful staining observed in paraffin-embedded human brain and tonsil tissues at 1:100 dilution using citrate buffer antigen retrieval. These tissue types represent distinct immunological microenvironments, suggesting versatility across sample contexts where IL-22 biology is relevant. The antibody is also validated for ELISA applications, providing flexibility for researchers who need both quantitative and spatial detection approaches within their experimental design.
Whether investigating IL-22's protective functions at barrier surfaces, its dysregulation in inflammatory bowel disease, or its emerging roles in tumor microenvironments, this antibody delivers the technical reliability needed for meaningful immunological research.
