The reaction was stopped by adding 25 pi EDTA and 25 pi TCA (trichloroacetic acid). The reaction mixture was then spotted on ionic paper (DEAE paper). The paper was washed three times with TCA and then with ethyl alcohol. The filter paper was air dried and put into a scintillation vial with a scintillation cocktail. Radioactivity was measured by a liquid scintillation counter (Blue Star). As a counting control, a blank silver composition was run through the complete procedure without viral load, to check any potential interference in the scintillation counter method.
