Abstract
A microtiter plate for blood typing consisting of a flat-bottomed plate of rigid transparent polystyrene having a plurality of wells, the polystyrene being surface treated by a corona and/or plasma method of applying high power electric energy at high frequency resulting in a permanently measurable negative ion-charge at the surface of the wells, and layers of substantially pure antiserums dried on the wells without any binder from a suspension or solution of the antiserums and tightly but releasably bound to the polystryene.
