METHOD AND APPARATUS FOR THE ANALYSIS OF BIOLOGICAL MATERIAL

摘要

2131090 9319199 PCTABS00025 A method for analysing material in a liquid sample, comprises the steps of: distributing the sample equally by passage through a number of discrete wells adapted to retain the material, the concentration of material being such that it is absent in at least one well; and analysing the wells for the presence of retained material. A device adapted for use in a method for analysing material in a liquid sample, comprises the combination of: a container for the sample; a unit comprising a number of discrete wells adapted to retain the material and allow the passage of liquid under the application of reduced pressure; means for drawing liquid from the container and through the wells under reduced pressure; and a manifold or other means that provides uniform distribution of the sample passing from the container into the wells.
