Used in biomedical research to quantify soluble ST2 levels in serum, plasma, or cell culture samples. Helps in studying inflammatory diseases, cardiovascular conditions such as heart failure, and immune responses. Commonly applied in clinical research to assess disease progression, risk stratification, and response to therapy. Also utilized in immunology studies to investigate the IL-33/ST2 signaling pathway’s role in allergic responses, asthma, and autoimmune disorders.
