ABSTRACT:
Attenuator compositions useful as reagents in an improved internal sample attenuator counting method for radioimmunoassays are described. These compositions comprise an attenuator material that have a high capacity to absorb emitted radiation from a radioligand of the radioimmunoassay and are combined with an immunologically reactive material which interacts with components of the radioimmunoassay or combined with an absorbent of the free radiolabelled component to separate bound from free radioligand.
