Abstract: The present disclosure provides a novel approach for shifting or distributing various information (e.g., protocols, analysis methods, sample preparation data, sequencing data, etc.) to a cloud-based network. For example, the techniques relate to a cloud computing environment configured to receive this information from one or more individual sample preparation devices, sequencing devices, and/or computing systems. In turn, the cloud computing environment may generate information for use in the cloud computing environment and/or to provide the generated information to the devices to guide a genomic analysis workflow. Further, the cloud computing environment may be used to facilitate the sharing of sample preparation protocols for use with generic sample preparation cartridges and/or monitoring the popularity of the sample preparation protocols.

The discovery UI allows interactive adjustment of the discovery criteria, displays the discovery list, and responds to selection of a discovered device in the discovery list by enabling a connection with the discovered device based on a network address of the discovered device obtained through one of the discovery protocols.

Abstract: The invention provides methods for generating a nucleic acid library. Target-specific primer-probes are hybridized to a target nucleic acid fragment to create a hybridization product. Each of the target-specific primer-probes comprises a target-specific sequence and a first adaptor sequence. The target nucleic acid fragment comprises a target genomic region of interest, wherein said target genomic region of interest comprises an exon of a gene and the target-specific primer-probes are tiled across the exon of the gene. The target nucleic acid fragment further comprises a second adaptor sequence different from said first adaptor sequence. Following hybridization, the target-specific primer-probes are extended to create double-stranded extension products and further amplified, thereby generating the nucleic acid library.

Abstract: A system allowing traders, etc. to use instant messaging (IM) (or other non-FIX based) communications to input trading instructions directly into a broker's Order Management System (OMS) for managing/executing trades. Accordingly, trading instructions may be provided electronically directly from a buy-side trader, and directly to a sell-side broker's/brokerage's OMS, without the need for the sell-side broker to manually re-key the order into the sell-side firm's OMS. Further, trading instructions are provided in electronic format directly to the broker's OMS without the need for the buy-side trader to have an expensive FIX based OMS or associated FIX connection, which is also expensive, thereby allowing relatively smaller investment houses/buy-side organizations to enjoy the benefits of electronic delivery of trading instructions directly to brokers' OMS.

Abstract: The invention provides methods for controlling the density of different molecular species on the surface of a solid support. A first mixture of different molecular species is attached to a solid support under conditions to attach each species at a desired density, thereby producing a derivatized support having attached capture molecules. The derivatized support is treated with a second mixture of different molecular species, wherein different molecular species in the second mixture bind specifically to the different capture molecules attached to the solid support. One or more of the capture molecules can be reversibly modified such that the capture molecules have a different activity before and after the second mixture of molecular species are attached. In particular embodiments, the different molecular species are nucleic acids that are reversibly modified to have different activity in an amplification reaction.
