Used in research settings to measure dehydroepiandrosterone sulfate (DHEA-S) levels in rat biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables scientists to study adrenal function, stress response, hormonal regulation, and aging-related processes in rodent models. It is commonly applied in endocrinology, neuroscience, and metabolic disease studies where DHEA-S serves as a biomarker for adrenal activity and overall physiological status. The assay provides a sensitive and specific quantitative analysis, supporting investigations into hormone-dependent behaviors, immune function, and the impact of pharmacological interventions.
