Abstract

An automated detection system includes a robotic fluid handling system for performing a plurality of assays; a detection system for imaging the assays as they are performed; and a computer control, data acquisition, and data analysis system for controlling the operation of the fluid-handling and detection system and for collecting and analyzing imaging data. The automated detection system comprises a pipettor for simultaneously distributing a predetermined amount of a liquid and a signal-generating element to each of the plurality of wells; an excitation source for simultaneously exposing the wells to excitation radiation; a detector for simultaneously detecting signal emitted from each of the wells over a period of time comprising a single imager for optically imaging the plurality of wells simultaneously; and computerized controller for simultaneously coordinating the pipettor, the excitation source, and the detector. Further, a method for performing simultaneous assays includes the steps of simultaneously distributing a predetermined amount of a liquid solution to each of a plurality of samples, simultaneously exposing the wells to excitation radiation, simultaneously detecting …
