Abstract

A sample solution is dripped on an injection region with a pipette. The sample solution immediately spreads in a reaction region by a capillary phenomenon. The sample solution is left for a predetermined period of time to bind a biological associated material in the sample solution with a specific affinity material bound on the inner surface of the reaction region. After the reaction, the outer surface portion of a support member is pushed against a reaction vessel main body to deform the support member, thereby bringing the sample solution into contact with a water absorbent member at a removal region. The sample solution is absorbed by the water absorbent member and is removed from the reaction region. A cleaning solution is dripped on the injection region in an appropriate amount to perform B/F separation and is allowed to spread in the reaction region. The cleaning solution is absorbed and removed by the water absorbent member. The biological associated material bound to the reaction region is assayed.
