Abstract:
Various embodiments of a sequencing system capable of rapidly imaging samples at multiple wavelengths are provided herein. In one embodiment, the system includes a fast- indexing filter wheel having a plurality of excitation and emission filters capable of being rapidly rotated into and out of communication with an excitation source (e.g., an arc lamp, a laser). For example, the filter wheel can be configured to index in an amount of time falling within a range of about 40 ms to about 60 ms, preferably 50 ms. The system can also be configured to account for vibrations resulting from the quick starts and stops of the fast- indexing filter wheel as well as vibrations resulting from other sources. Various methods of rapidly imaging a sample at multiple wavelength are also provided herein.

Various flowcell configurations and systems are provided as are methods of making and using same. The flowcells, systems, and methods of use can be useful in carrying out sequencing reactions and next generation sequencing methods.
Abstract:
Systems and methods for multiple analyte detection include a system for distribution of a biological sample that includes a substrate, wherein the substrate includes a plurality of sample chambers, a sample introduction channel for each sample chamber, and a venting channel for each sample chamber. The system may further include a preloaded reagent contained in each sample chamber and configured for nucleic acid analysis of a biological sample that enters the substrate and a sealing instrument configured to be placed in contact with the substrate to seal each sample chamber so as to substantially prevent sample contained in each sample chamber from flowing out of each sample chamber. The substrate can be constructed of detection-compatible and assay-compatible materials.
