  • Patent number: 6045754
    Abstract: The present invention relates to a field kit for the detection of analytes and to a method for using such a field kit. The field kit comprises a tray and lid adhered to the surface of the tray. Reaction-reagent compartments are formed by recesses in the tray when the tray is adhered to the lid. Probe compartments may also be included if desired. In operation, the tray and lid are bent at a score line to open the wells containing the reaction reagents. The lid is bent to form an A-shaped structure so that the kit may be placed in an upright position for use. A portion of the lid is peeled back from the tray to release probes and other, non-liquid components, if present.
