Used in research settings to quantify Cyclosporin A levels in rat biological samples such as blood, plasma, or tissue homogenates. This ELISA kit enables precise measurement of CsA concentrations, supporting studies on drug metabolism, immunosuppression, and organ transplant rejection in rat models. It is particularly valuable in pharmacokinetic and toxicology studies where accurate monitoring of drug levels is critical. The assay is sensitive, specific, and designed to minimize cross-reactivity with structurally similar compounds, ensuring reliable data in preclinical research.
