Abstract

1358827 Determination of human carcinoembryonic antigen material F HOFFMANN - LA ROCHE & CO A G 1 June 1971 [1 June 1970 27 Jan 1971 12 April 1971] 44185/73 Divided out of 1356911 Heading G1B Human carcinoembryonic antigen (CEA) material in blood is detected by a method comprising (a) adding a measured amount of antibody to the CEA material to a solution of a purified perchloric acid extract of blood serum or blood plasma in a buffered solvent; (b) incubating; (c) adding a measured amount of radioactively tagged CEA material; (d) incubating; (e) adding a precipitating agent, for example zirconyl phosphate gel, to precipitate antigen-antibody complexes; (f) measuring the radio-active content of the resulting precipitate. The initial serum or plasma sample may be treated with at most 1.2M perchloric acid and centrifuged, the supernatant then being purified by dialysis. In an example goat antiserum is used in step (a).
