ABSTRACT:
Method for detection of a biological material in a sample. The method includes the steps of liquifying the sample (if necessary) and pouring the liquified sample into the incubation plate. The incubation plate has a generally flat horizontal surface and the surface is divided into a plurality of at least 20 recessed wells. Each well is adapted to hold an aliquot of liquid and is sized and shaped, and formed of a suitable material, to hold the aliquot within the well by surface tension. Any excess liquid from the liquified sample is poured from the surface of the plate. The method then involves incubating that incubation plate until the presence or absence of the biological material is determined.
