Abstract: The invention relates to a pharmaceutical composition for prophylactic and/or therapeutic treatment of patients for immunization against a virus infection and is characterized in that this is obtainable by neutralizing the enriched and/or purified virus with antibodies. The invention further comprises a kit for the production of this composition as well as the use of a virus neutralized with antibodies for the production of a pharmaceutical composition.

Abstract: A cage structure for restraining primates includes a bottom of rectangular ground plan and formed by rods or tubes, side walls surrounding the bottom, and a ceiling. A cage structure of this type is to be manufacturable in any desired size and at low an expenditure as possible. The cage develops only low levels of noise. To this end, only one of the side walls, i.e., the front wall, is formed by rods or tubes, while the remaining three side walls and the ceiling are made of concrete or brickwork having their interior surfaces smoothed. The wall opposite the front wall, i.e., the rear wall, is displaceable towards and away from the front wall. At least one side wall and the ceiling incorporate inspection panes made of bullet-proof glass.

Abstract: A low-voltage apparatus for demonstrating antigens in body liquids by cross-migration electrophoresis. The apparatus comprises a container filled with a buffer solution, which container has an anode and a cathode chamber and houses a gel-carrying tray. Recesses for receiving antigens and antibodies are provided in the gel and arranged to lie opposite each other in pairs at a distance of between 2 and 5 mm. The gel has a horizontal heat-exchange surface area of at least 50 cm.sup.2. The gel layer reaction zone between the recesses is between 0.5 and 1.5 mm thick and has a cross-sectional area of between 100 and 150 mm.sup.2. The apparatus permits a current passage of 100 milliampere, resulting in a current density of 0.7 milliampere/mm.sup.2 in the gel layer reaction zone.
