title: Evaluation of a commercial enzyme radioimmunoassay kit for serum carcinoembryonic antigen.
abstract: An enzyme immunoassay kit for carcinoembryonic antigen (CEA) that uses plastic beads coated with guinea-pig anti-CEA as first antibody and goat anti-CEA conjugated with horseradish peroxidase as second antibody has been evaluated. The method does not involve perchloric acid extraction and therefore avoids a dialysis procedure. It is accurate, sensitive, and inexpensive to operate, and provides values comparable to those obtained with the Roche-CEA Z-Gel radioimmunoassay.
