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. Also described are graphical user interfaces that present a user with the options to select a first microplate having a plurality of wells, associate at least one probe material with one or more of the wells, and associate one or more locations on one or more substrates with the one or more wells.

High throughput microarray spotting system and method

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.

System, method, and product for dynamic noise reduction in scanning of biological materials

Systems and methods are described that may be applied to scanning biological materials in or on probe arrays. For example, a system is described that includes a scanner that has one or more excitation sources and an emission receiving element, such as an objective lens, that receives from locations of the probe array an emission signal responsive to the excitation sources. The scanner also has a radial position generator that generates radial positions of the emission receiving element. Also included in the system is a computer memory having stored therein a plurality of position data, each representing a radial position of the emission receiving element. Also stored in the computer memory unit is a set of comparator instructions that generate a clock signal based, at least in part, on comparing one or more of the plurality of radial positions with one or more of the plurality of position data.
