Used in biomedical research to quantify Neurkinin B (NKB) levels in human biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly valuable in studies related to reproductive health, neuroendocrinology, and hypothalamic function. Researchers use it to investigate conditions like Kallmann syndrome, idiopathic hypogonadotropic hypogonadism, and menopausal disorders, where NKB signaling plays a regulatory role. The kit enables high sensitivity and specificity in detecting NKB concentration changes, supporting both clinical diagnostics research and drug development targeting the NKB receptor pathway.
