Radioimmunoassay of digoxin employing charcoal entrapped in magnetic polyacrylamide particles.
Charcoal and magnetisable ferric oxide were entrapped in a polyacrylamide gel and, after lyophilisation and micronisation, empolyed for the uptake of free antigen in a radioimmunoassay for digoxin. The results obtained were similar to those using a conventional charcoal separation method.
