Abstract
The authors describe a method for isolation of Toxoplasma gondii antigenic membrane components. Technical work is described into four points: 1) specific labelling of membrane proteins was realised by DD125ISA; 2) methacrylate microspheres were bound to unbroken toxoplasma membranes by the mean of an indirect technic with antibody molecules (double sandwich); these microspheres were used to modify the membrane density; 3) toxoplasmas bound to microspheres were broken by sonication; 4) microspheres fixed to membrane components were isolated by isopycnic ultracentrifugation on continuous sucrose gradient.
