  • Methods, systems and solid compositions for reagent delivery
    Patent number: 11686738
    Abstract: Methods, systems, and compositions featuring a solid, dissolvable reagent composition for delivering the reagent, such as an antibody, probe, chromogen, etc., to a sample. The present invention also features methods of producing said compositions, and automated systems featuring the use of the solid, dissolvable reagent compositions. The solid, dissolvable reagent composition may comprise a water-soluble polymer film, such as a polyvinyl alcohol film, infused with the reagent, wherein when applied to the sample, the water-soluble polymer film with reagent contacts the sample (e.g., tissue) and dissolves.
    Type: Grant
    Filed: September 28, 2021
    Date of Patent: June 27, 2023
    Assignee: Ventana Medical Systems, Inc.
    Inventors: Anisha Anand, Crystal L. Stephens, Natcha Suriyavirun
