Used in biomedical research to measure adrenaline (epinephrine) levels in rat biological samples such as plasma, serum, or tissue homogenates. This assay is commonly applied in studies related to stress response, adrenal gland function, neuroendocrinology, and sympathetic nervous system activity. It enables researchers to quantify adrenaline with high sensitivity and specificity, supporting investigations in pharmacology, physiology, and behavioral science. The kit is intended for research use only and not for diagnostic purposes in humans.
