title: Preparation of carbon-14-labelled whole short ragweed pollen antigens.
abstract: A new method of labelling short ragweed pollen antigens with carbon-14 is described. The known ragweed antigens AgE, Ra3, Ra5 and several other antigens are radiolabelled. These components are biologically active, have a high specific radioactivity and a long half-life.
