  • Patent number: 12186755
    Abstract: Described herein are multi-well separation devices configured to allow a composition comprising a target agent to be separated into multiple wells, subdivided, recombined into a single well, and/or re-separated into the same or a different configuration of wells. Also described herein are reagent loading devices configured to simultaneously deliver one or more test agents to a plurality of volumes without having to individually deliver the test agents. Together, these devices allow high throughput parallel processes without repetitive pipetting or liquid handling robotics, though they may also be used separately. Also described herein are kits and systems for chemical or biological assays, as well as methods for using the multi-well separation devices and reagent loading devices described herein.

  • Publication number: 20240254536
    Abstract: Described herein are reagent loading devices configured to simultaneously deliver one or more test agents (e.g., antibiotics) to a sample such as a bacterial culture without having to individually deliver the test agents. These devices allow high throughput parallel processes without repetitive pipetting or liquid handling robotics. Also described herein are kits and systems for chemical or biological assays.

  • Publication number: 20240041801
    Abstract: The present disclosure provides methods of treating coronavirus-associated diseases in an individual comprising administering to the individual an effective amount of peramivir, cidofovir, or nevirapine and an effective amount of a second antiviral agent. Also provided are methods of treating coronavirus-associated diseases in an individual comprising administering to the individual an effective amount of nevirapine and an effective amount of valacyclovir and/or nevirapine. Also provided are formulations and methods of delivering the formulations to an individual.

  • Publication number: 20220331796
    Abstract: The transfer systems, devices, kits, and methods described here may be used to facilitate the transfer of a material (e.g., a fluid) to or from a donor container, e.g., to or from wells of a donor plate while leaving target agents attached to the wells. The systems may comprise a donor plate, a transfer adapter, and a receiver plate that may be coupled to form a transfer assembly. The transfer adapter may comprise a planar sheet and a plurality of openings, and it may be configured to regulate the flow of fluid out of the wells. The transfer assembly may be placed into a centrifuge, and the fluid transfer force produced by the centrifuge may cause fluid to flow out of the wells of the donor plate, through the openings in the transfer adapter, and into the receiver plate.
