Used in biomedical research to detect and quantify levels of glycogen phosphorylase isozyme BB in human samples, particularly in studies related to myocardial injury and brain damage. Due to its specificity for cardiac and neuronal tissues, this ELISA kit helps researchers assess tissue-specific damage in conditions like acute myocardial infarction, stroke, or hypoxic injury. It is also employed in clinical research to explore GP-BB as a potential biomarker for early diagnosis and monitoring of ischemic events. The assay provides a sensitive and reliable method for measuring low concentrations of GP-BB in serum or plasma, supporting investigations into cellular energy metabolism and tissue stress responses.
