ABSTRACT
The synthetic ACTH peptides β1–39 and β1–24 stimulated lipolysis as determined by the rat epididymal fat pad in vitro. The stimulating effect of these peptides was diminished by prior incubation of the peptides with antibodies produced by the guinea-pig against ACTH. The stimulating effect of these hormones was also diminished by the double antibody system used in the radio-immunoassay of ACTH and other peptide hormones, in which incubation with antiserum is followed by precipitation of the antigen-antibody complex by rabbit anti-guinea-pig-γ-globulin.
