The Lactate Dehydrogenase (LDH) Activity Assay Kit is widely used in biomedical research and clinical diagnostics to measure LDH activity in various biological samples. It is particularly valuable in assessing cell viability and cytotoxicity, as LDH is released into the culture medium upon cell membrane damage. This kit is also employed in studying tissue damage, as elevated LDH levels in blood serum can indicate conditions such as myocardial infarction, liver disease, or hemolysis. Additionally, it is utilized in cancer research to monitor tumor cell response to therapeutic agents. The assay is essential in toxicology studies for evaluating the impact of drugs or chemicals on cellular health. Its simplicity, sensitivity, and reliability make it a preferred tool in both research and diagnostic laboratories.
