title: Formaldehyde-ozone-induced fluorescence and ACTH immunoreactivity in basophil tumours of the pituitary.
abstract: The ACTH cells of human foetal pituitary displayed intense formaldehyde-ozone-induced fluorescence characteristic of peptides or proteins with NH2-terminal tryptophan. Fourteen pituitary tumours were examined histochemically. Of these, two displayed formaldehyde-ozone-induced fluorescence. These two tumours were the only ones to exhibit ACTH immunoreactivity.
