Rat Growth Hormone: Immunofluorescent and Radioimmunologic Studies

Abstract
The cross-reactivity that exists between antisera to porcine growth hormone and rat growth hormone and the successful radioiodination of rat growth hormone have permitted the development of a sensitive radioimmunoassay for rat growth hormone. Human growth hormone does not cross-react in this system. By fluorescent techniques the anti-PGH serum has been found to stain the acidophiles of the rat pituitary, a finding which provides further evidence of crossreactivity with rat growth hormone.
