Used in research settings to quantify levels of Human Erythromycin-N-demethylase (ERND) in biological samples, this ELISA kit enables the study of enzyme activity related to erythromycin metabolism. It is particularly valuable in pharmacological and metabolic studies investigating drug processing in the liver, especially cytochrome P450-mediated pathways. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for clinical research, toxicology studies, and drug development where monitoring metabolic enzyme expression is critical. Results aid in understanding individual variations in drug response and potential drug-drug interactions.
