| Antigen: CRH Antigen species: not specified Source (producer): specified elsewhere Primary antibody: rabbit antiserum Primary antibody species: rabbit Antibody type (monoclonal, polyclonal): polyclonal Secondary antibody: goat-antirabbit Secondary antibody species: goat Immunoglobulin class: IgG Control: staining pattern Visualization method: autoradiogram Visualization medium: slide Annotation: Up to five one-in-five series of ...sections through the PVH were saved and then prepared for indirect immunofluorescence staining of cells that cross-react with antisera against CRF, neurotensin, oxytocin, or vasopressin using a conventional method (Sawchenko and Swanson, 1981) based upon the localization of a primary antiserum raised in rabbits using an affinity-purified, fluorescein-conjugated goat anti-rabbit IgG. To ensure the validity of our localization of CRFimmunoreactive neurons, three sera against CRF human alpha-globulin conjugates were used. Two of these (C24 and C30) are directed against the C- and N-terminal portions, respectively, of the ovine CRF molecule (Swanson et al., 1983; Vale et al., 1983). The third was prepared against a synthetic rat CRF (Rivier et al., 1983) conjugate. Each of these sera was used at a final dilution of 1:3000, and pre-incubation of each with 22 mg ml-l of the respective immunogen blocked specific staining of cells and fibers in the hypothalamus. All sera used for both normal immunohistochemistry and blocking experiments contained 10 mg/ml of the “carrier” protein used for immunization.
| | Antigen: neurotensin Antigen species: N/A Source (producer): Dr. M. R. Brown (Peptide Biology Laboratory, The Salk
Institute) Primary antibody: neurotensin antiserum Primary antibody species: not specified Antibody type (monoclonal, polyclonal): monoclonal Secondary antibody: not specified Secondary antibody species: not specified Immunoglobulin class: not specified Control: staining pattern Visualization method: autoradiogram Visualization medium: slide Annotation: Dr. M. R. Brown (Peptide Biology Laboratory, The Salk Institute) and was prepared against neurotensin conjugated with glutaraldehyde to thyroglobulin. This serum (Nil-1) is directed against the C-terminal portion of the molecule (Brown et al., 1978) and was used at a dilution of 1:4000. All staining in the hypothalamus was blocked by the addition of synthetic neurotensin (15 mg/ml) to the serum.
