Novel devices and techniques for carrying out immunoassay techniques on antibodies, antigens or haptens are provided herein. The device is a macroporous hydrophobic synthetic polymer cloth having antibodies or antigens directly adsorbed therein and directly absorbed and immobilized thereon. The cloth has a thickness more than 200.mu.m and having spaces between fibres exceeding 20.mu.m in diameter, and preferably has a Frazier Air permeability, in CFM/ft2 at 0.5" H2O of from 215 to 750 for thickness of from 11 to 40 mils, the cloth thereby having a structure such that it can accommodate a large volume of liquid per surface area thereof, that it has a large surface area, and that it has minimum flow resistance. In addition, in two alternative embodiments: antibodies may be directly adsorbed therein and directly absorbed and immobilized thereon, and specific antigens from a selected test sample, may then be captured by the adsorbed, absorbed and immobilized antibodies, to be detected conventionally; or antigens may be directly adsorbed therein and directly absorbed and immobilized thereon, and specific antibodies from a selected test sample, may be captured by the adsorbed, absorbed and immobilized antigens, to be detected conventionally.
