Used in diagnostic assays to detect and quantify secretory phospholipase A2 group IB (sPLA2-GIB) in biological samples. Enables research on pancreatic function and inflammation-related diseases. Supports development of targeted therapies by neutralizing sPLA2-GIB activity in preclinical studies. Applied in immunoassays and immunohistochemistry for biomarker validation. Facilitates monitoring of disease progression in conditions linked to elevated sPLA2-GIB, such as acute pancreatitis and atherosclerosis.
