Abstract
Products are prepared of solid hydrogel matrixes having entrapped therein high-surface area sorbent materials, preferably activated carbon. The entrapped absorbent has an effective surface area no greater than about 1% of the actual surface area of the sorbent material, e.g., activated carbon per se, preferably not over 0.001%. The products are particularly useful in radioimmunoassay for antigens.
