Summary: The distribution of corticotropin-releasing hormone (CRH) in the brain and pituitary of the hagfish Eptatretus burgeri, representing the earliest branch of vertebrates, was examined by immunohistochemistry to better understand the neuroendocrine system of hagfish. A rabbit polyclonal antibody raised against human/mouse/rat CRH (Cat. #AB-02) was used. A standard curve was obtained from 0.78 ng/ml to 50 ng/ml. The cross-reactivity of anti-CRH antibody against CRH family peptides was found to be less than 0.01%, indicating the specificity of the antibody. The specificity of the antibody raised against human/mouse/rat CRH was demonstrated by a TR-FIA and absorption test. CRH-ir cell bodies were detected in two brain regions; the preopticohypothalamic area (PO, POp, and Hyinf) and the medulla oblongata. CRH-ir fibers were mainly distributed in the hypothalamus and the medulla oblongata, in which CRH-ir cell bodies were detected.
