Rapid plunger immunoassay method and apparatus

摘要

A method and apparatus for conducting an immunoassay. The apparatus features a cylindrical tube having one open end into which a plunger filter assembly is slidably fitted. The filter assembly is composed of a plunger filter cylinder open at both ends, a seal fixed to the proximal end of the plunger filter cylinder and a dome-shaped filter inside of and closing the proximal end of the plunger filter cylinder, and beads sensitized with an immunologically reactive material, such as an antibody.
