  • Patent number: 11774443
    Abstract: The method involves drying down dye-conjugated reagents in separate locations in a reaction vessel so that the dyes don't non-specifically interact with each other during drying. This invention thus improves multiplex binding assays by eliminating erroneous results caused by dyes' being non-specifically attached to each other when dried down together.
