A new method is demonstrated for the separation of free and bound fractions in a wide range of immunoassays without the need for centrifugation and decantation. The method employs a novel separator device which, in conjunction with any choice of separating reagent, allows all manipulations to be performed in a single tube simply, rapidly, and safely. The system has potential applications in other fields involving mass transport through selective barriers.
