Used in biomedical research to quantify levels of serum amyloid A1 (SAA1) in human biological samples such as plasma, serum, or cell culture supernatants. This kit is essential for studying inflammatory processes, as SAA1 is an acute-phase protein that increases significantly during inflammation, infection, or tissue injury. Researchers use this assay in clinical studies related to chronic inflammatory diseases, including rheumatoid arthritis, atherosclerosis, and certain cancers, to monitor disease progression and response to therapy. It is also employed in diagnostic development and biomarker validation due to its high sensitivity and specificity for detecting low concentrations of SAA1.
