Used in biomedical research to quantify levels of the S100A8/A9 protein complex in biological samples such as serum, plasma, and cell culture supernatants. This kit is particularly valuable in studies related to inflammation, autoimmune diseases, and cancer, as S100A8/A9 is a biomarker associated with neutrophil activation and inflammatory responses. Researchers use it to monitor disease progression, evaluate therapeutic efficacy, and investigate the role of this protein complex in conditions like rheumatoid arthritis, sepsis, and inflammatory bowel disease. The ELISA format allows for high sensitivity and specificity, making it suitable for both clinical and experimental settings.
