Выделение антигенов из пузырей Echinococcus granulosus методом ступенчатой мембранной фильтрации

Isolation of antigens from echinococcus granulosus cysts by gradual membrane filtraion

High molecular fractions were obtained by gradual memnrane diafiltration and their antigenic and enzymatic (carboxylesterase) activity were analyzed. Degree of the fractions' homogeneity was determined by high performance liquid chromatography. Active antigenic complexes were discovered in fractions with m. m. over 300.000 and 100.000=300.000.
