title: Monomeric pituitary growth hormone and prolactin variants in man characterized by immunoperoxidase electrophoresis.
abstract: Immunoperoxidase electrophoresis, combining SDS--ME--PAGE and the 'double bridge' immunoperoxidase staining was applied to crude human pituitary homogenates. With anti-hGH and anti-hPL sera, 4 hGH-related monomers were characterized: a Mr 22 000 peptide corresponding to hGH; a Mr 20 000 peptide corresponding to the known hGH variant and two unknown hGH variants (Mr 65 000 and Mr 75 000). With anti-ovine, rat and human PRL sera, 4 PRL-related monomers were immunostained: one comigrated with purified hPRL (Mr 25 000), and 3 were unknown (Mr 29 000; Mr 45 000; Mr 16 000).
