Used in biomedical research to measure doxorubicin (ADR) levels in rabbit biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to quantify drug concentration for pharmacokinetic studies, helping assess drug metabolism, distribution, and clearance in preclinical animal models. It supports evaluation of targeted drug delivery systems, especially in cancer research where doxorubicin is used as a chemotherapeutic agent. The assay provides a sensitive and specific method to monitor ADR exposure in experimental treatments, aiding in toxicity studies and dosage optimization.
