Used in biomedical research to quantify beta-endorphin levels in mouse biological samples such as plasma, serum, or tissue homogenates. This ELISA kit enables researchers to study the role of beta-endorphin in stress responses, pain modulation, addiction, and neuroendocrine function. It is widely applied in neuroscience, immunology, and behavioral studies where accurate measurement of this endogenous opioid peptide is required. The assay provides high sensitivity and specificity, allowing detection of subtle changes in beta-endorphin concentrations across experimental conditions.
