Used in biomedical research to quantify levels of lactate dehydrogenase B (LDHB) in human samples such as serum, plasma, or cell lysates. This kit enables researchers to study LDHB expression in various physiological and pathological conditions, including cardiovascular diseases, cancer metabolism, and metabolic disorders. It is particularly valuable in studies involving the regulation of anaerobic glycolysis and oxidative phosphorylation. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for clinical research and drug development where monitoring enzyme levels can reflect tissue damage or tumor progression.
