Abstract: A method of loading beads on a sensor substrate includes applying a suspension including beads to a flow cell defined over a sensor substrate. The sensor substrate includes a plurality of wells. The beads at least partially deposit into the plurality of wells. The method also includes removing liquid from the flow cell, evaporating liquid from the flow cell, for example, by drawing air through the flow cell; and applying a hydrating solution to the flow cell.

Abstract: Disclosed herein are conjugates comprising a biomolecule linked to a label that have biological activity and are useful in a wide variety of biological applications. For example, provided herein are polymerase-nanoparticle conjugates including a polymerase linked to a nanoparticle, wherein the conjugate has polymerase activity. Such conjugates can exhibit reduced aggregation and improved stochiometries wherein the average biomolecule:nanoparticle ratio approaches or equals 1:1. Also disclosed herein are improved methods for preparing such conjugates, and methods and systems for using such conjugates in biological applications such as nucleotide incorporation, primer extension and single molecule sequencing.

Abstract: Compositions, systems and methods of sequencing are disclosed, where the compositions and systems include polymerase enzymes that have been genetically modified to more efficiently incorporate nucleotides including labels having a detectable properties that are released during incorporation, to augment a rate of labeled nucleotide incorporation, to augment a rate of pyrophosphate release, or to augment two or more of these properties and rates. Also disclosed are terminally labeled and dual labeled nucleotides, and click-chemistry based methods of synthesizing the same.
