title: Preparation of anti-etiocholenic acid antiserum and anti-cholesterol succinate antiserum and their cross reactivities.
abstract: Anti-3-hydroxy 5-androstene carbonic acid (etiocholenic acid) antiserum was obtained by immunizing rabbits with anetiocholenic acid-polylysine complex. Anticholesterol succinate antiserum was also prepared by immunizing rabbits with a cholesterol succinate-polylysine complex. The cross reactivities of these antisera were examined by means of radioimmunoassay system, immunolysis of liposome and passive hemagglutination reaction. Anti-etiocholenic acid antiserum was specific against the structure of ring A of cholesterol and the nature of OH group at C3 position and anti-cholesterol succinate antiserum was specific against the side chain similar to that of cholesterol.
