  • Patent number: 11383234
    Abstract: Various aspects of the present invention relate to the control and manipulation of fluidic species, for example, in microfluidic systems. In one aspect, the invention relates to systems and methods for making droplets of fluid surrounded by a liquid, using, for example, electric fields, mechanical alterations, the addition of an intervening fluid, etc. In some cases, the droplets may each have a substantially uniform number of entities therein. For example, 95% or more of the droplets may each contain the same number of entities of a particular species. In another aspect, the invention relates to systems and methods for dividing a fluidic droplet into two droplets, for example, through charge and/or dipole interactions with an electric field. The invention also relates to systems and methods for fusing droplets according to another aspect of the invention, for example, through charge and/or dipole interactions. In some cases, the fusion of the droplets may initiate or determine a reaction.

  • Publication number: 20220056516
    Abstract: Method and apparatus to facilitate separation of solution-phase components surrounding an immobilized multicomponent complex while stabilizing association of the components within the complex. The technique can be used for reducing background signal arising from the presence of non-complexed components harboring detectable labels, thereby enhancing signal-to-background ratios and allowing enhanced detection of the multicomponent complex.

  • Publication number: 20210340612
    Abstract: Method and composition for identifying cognate nucleotides in a Sequencing By Binding™ procedure, wherein one or more labeled nucleotides are detected in ternary complexes but never incorporated. Labeled nucleotides can be incorporable nucleotides that contact preformed blocked primed template nucleic acids. Alternatively, labeled nucleotides are labeled non-incorporable nucleotides. Labeled nucleotides, including labeled non-incorporable nucleotides, can be detected in ternary complexes in the same reaction mixture that incorporates a reversible terminator nucleotide to create a blocked primed template nucleic acid. Detection of ternary complexes can take place in the presence of a catalytic metal ion.

  • Publication number: 20200333334
    Abstract: The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalising the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.
