Abstract: The invention relates generally to the field of automated collection and deposition of fluid, semi-solid, and solid samples of biological or chemical materials. More specifically, the invention relates to the field of microarrayers, which are devices for autonomously depositing minute droplets of biological or chemical fluid samples in ordered arrays onto substrates. The invention also relates to tissue arrayers, which are devices for the collection and deposition of solid and semi-solid tissue samples in ordered arrays. Other aspects of the invention relate to fluidics robots, which are devices for the autonomous collection, dispensing and processing of biological or chemical fluid samples. The invention improves the throughput of microarrayers, tissue arrayers, and fluidics robots by providing methods and apparatuses to precisely and repeatably load supplies into the machines.

Abstract: A system is described for automatic retrieval of microplates from a carousel. The system includes an effector arm that retrieves a selected microplate from the carousel, a microplate retainer that receives the selected microplate from the effector arm, and a controller that directs the effector arm to the carousel for retrieval of the selected microplate and directs the effector arm to the microplate retainer so that it may receive the selected microplate. The carousel may revolve around a vertical axis. A system also is described for washing depositing elements used to spot biological materials on a substrate. Graphical user interfaces also are described for enabling a user to determine which microplates will be used to provide biological probe materials, and in what patterns those probe materials should be deposited on the substrate. The interfaces enable the user to place multiple fractions of biological materials on a same location on a substrate.

Abstract: Systems and methods are described for processing an emission signal, such as a fluorescent signal, to compensate for noise in an excitation beam, such as a laser beam. As one example, a scanning system is described that includes an excitation signal generator that provides an excitation signal having one or more representative excitation values representative of an excitation beam; an excitation reference provider that provides at least one excitation reference value; a normalization factor generator that compares the excitation reference value to at least one representative excitation value, thereby generating a normalization factor; and a comparison processor that adjusts at least one emission value corresponding to the at least one representative excitation value based, at least in part, on the normalization factor.
