Used in biomedical research to quantify levels of human α-endomorphin (α-EP) in biological samples such as plasma, serum, cerebrospinal fluid, and tissue homogenates. This ELISA kit enables researchers to study the role of α-EP in pain modulation, stress response, and opioid-related pathways. It is particularly useful in neuroscience and endocrinology studies investigating endogenous opioid systems. The assay provides high sensitivity and specificity, allowing accurate measurement even at low concentrations. It supports research into chronic pain conditions, addiction mechanisms, and potential therapeutic targets within the opioid receptor system. Not intended for diagnostic or therapeutic use.
