Used to measure interleukin-22 (IL-22) levels in human biological samples such as serum, plasma, or cell culture supernatants. It is commonly applied in immunological research to study inflammatory diseases, autoimmune conditions, and immune responses. The kit helps in understanding the role of IL-22 in conditions like psoriasis, inflammatory bowel disease, and respiratory infections by providing a reliable and sensitive method for quantifying protein concentration. It is widely used in clinical labs and pharmaceutical research for biomarker analysis and drug development.
