Used in biomedical research to detect and quantify levels of heart-type fatty acid binding protein (h-FABP) in human serum, plasma, or tissue samples. This kit is particularly valuable in early diagnosis of acute myocardial infarction (heart attack), as h-FABP is rapidly released into the bloodstream following cardiac injury. It serves as a sensitive biomarker for myocardial damage, often appearing earlier than traditional markers like troponin. Researchers also use this ELISA kit in studies related to cardiovascular risk assessment, ischemic heart disease, and heart failure. The assay supports high-throughput screening in clinical labs and research settings, enabling accurate, reproducible results for early cardiac biomarker detection.
