<p>Invention relates to improvements in the detection of the presence of complementary agents in samples, particularly extractable nuclear antigens, by monitoring the formation of a precipitate or light scattering matrix. The method and apparatus are particularly concerned with the control of the application of the samples to a test body (11), normally a gel. By applying the samples to the surface of a test body and removing excess liquid, the permeation of particulate matter into the test body can be substantially eliminated. In conventional methods such matter can smother the results of a test. The careful control of the regions to which the samples are applied has further useful advantages in speed and improved detectability when the effective separation of the samples are reduced by interlocking the sample application regions. A mask is proposed as the most advantageous method of controlling the regions of application.</p> |
