Abstract: A reagent storage and dispensing apparatus comprises a housing, storage wells disposed within an internal volume of the housing, and a valve. The housing comprises a shared outlet chamber. The wells can be selected to be in fluid communication with the shared outlet channel through individual outlet channels. The valve is coupled to the housing and is rotated to select a well to be in fluid communication with the shared outlet channel while preventing the remaining wells from being in fluid communication. As the valve is rotated, the wells and their individual outlet channels remain stationary. To dispense fluid from or draw fluid into the selected well, positive or negative pressure, respectively, is introduced into the internal volume. Pressurization of the internal volume also pressurizes the plurality of wells, though the valve allows only fluid flow for the selected well.
Abstract: The present disclosure provides methods, device, and system for wafer processing. The wafer processing apparatus uses lid dispenser to disperse at least one reagent to the surface of the wafer. Further, the wafer is positioned on top of a rotatable vacuum chuck configured to spread at least one reagent over the surface of the wafer via a centrifugal force or surface tension, thereby permitting the at least one reagent to react with an additional reagent. Further, when dispensing the at least one reagent, a separation gap between the lid dispenser and the wafer is at a predetermined distance, for example, from 50 ?m to 2 mm.

Abstract: The present invention relates generally to methods of sequencing of polynucleotides and compounds, compositions and kits useful for sequencing of polynucleotides. The chemical compounds include nucleotide and nucleoside analogs which possess a blocking group covalently attached to the 3? hydroxyl of the sugar moiety. The blocking group may optionally be additionally covalently attached to a linker and/or detectable label. The nucleotide analogs may be ribonucleotide or deoxyribonucleotide analogs. Methods include incorporation of the reversible terminator molecules into growing polynucleotide strands by polymerase enzymes, such as in single base sequencing methodologies utilizing sequential reversible termination techniques.
