Used in biomedical research to quantify levels of soluble phospholipase A2 in human biological samples such as serum, plasma, or cell culture supernatants. This assay helps investigate inflammatory processes, as sPL-A2 is involved in conditions like rheumatoid arthritis, sepsis, asthma, and atherosclerosis. Researchers use the kit to assess disease progression, evaluate therapeutic responses, and explore the role of sPL-A2 in immune regulation and lipid metabolism. The ELISA format allows for high sensitivity and specificity, making it suitable for clinical and experimental studies focused on inflammation and related pathologies.
