Used in research to quantify RFRP-3 peptide levels in biological samples such as serum, plasma, or tissue homogenates. Enables study of reproductive physiology and neuroendocrine regulation in rodent models. Commonly applied in studies related to puberty, gonadotropin release, stress response, and seasonal breeding. Supports investigation of hormonal pathways involving gonadotropin-inhibitory hormone (GnIH) signaling. Suitable for use in preclinical research and endocrinology studies requiring sensitive and specific detection of RFRP-3.
