Levels of corticotropin releasing factor-like immunoreactivity in mammalian hypothalamic and extrahypothalamic brain tissue as determined with a monoclonal antibody to the ovine material

CS Hollander, T Audhya, M Russo, J Passarelli, T Nakane and D Schlesinger

A monoclonal antibody to ovine corticotropin releasing factor (CRF) has been produced by fusion of a non-producing plasmacytoma cell line P3U1 with spleen cells of Balb/c mice immunized with the synthetic 41 amino acid peptide coupled covalently with rabbit myosin by a heterobifunctional reagent, N-succinimidyl 3-(2-pyridyldithio) propionate. A total immunizing dose of 500 micrograms resulted in a highly specific, high-affinity antibody with a Ka of 0.15 x 10(12) M-1, which was used to establish a specific RIA with a sensitivity of 10 pg/tube. Levels of corticotropin releasing factor-like immunoreactivity (CRF-LI) in a pg/mg of hypothalamic tissue ranged from 4-10 in ovine, 2.5-8 in bovine, 47.5-67.5 in mouse and 2.3-20 in human tissue. Moreover, CRF-LI was widely distributed in extrahypothalamic mouse brain at concentrations approximately one half those seen in hypothalamus.
