Used in biomedical research to measure adenosine diphosphate (ADP) levels in human biological samples such as plasma, serum, or cell lysates. The kit enables researchers to quantify ADP concentrations accurately, supporting studies related to platelet activation, blood coagulation, and energy metabolism. It is commonly applied in cardiovascular research, particularly in evaluating antiplatelet therapies and thrombotic disorders. The assay is also useful in metabolic and cellular function studies where ADP/ATP ratios are indicators of cellular energy status. Due to its high sensitivity and specificity, this ELISA kit is preferred in clinical labs and pharmaceutical research for reliable data in diagnostic and drug development settings.
