Glucagon from avian pancreatic islets: radioreceptor studies.
Glucagon extracted from isolated islets of the pigeon was studied by means of Sephadex gel filtration. Radioreceptor assay, using rat liver plasma membranes and radioiodinated porcine glucagon, showed that the bulk of the activity eluted with glucagon (molecular weight 3500). Avian glucagon appeared to be less effective than porcine glucagon in inhibiting the binding of labeled porcine glucagon to rat plasma membranes.
