Abstract: The disclosure relates to methods and compositions for evaluating emulsion uniformity. In an exemplary embodiment, the disclosure provides a method for evaluating a quality characteristic of a droplet. The method includes the steps of: encapsulating a plurality of polynucleotides in a droplet, wherein the plurality of polynucleotides comprises at least one species of oligonucleotide; tagging the polynucleotides with a label that identifies the polynucleotides as arising from the droplet; counting a number of species of oligonucleotide tagged with the label; and determining a quality characteristic of the droplet based on the number of species of oligonucleotide tagged with the label. The oligonucleotide may include a first nucleic acid segment and a second nucleic acid segment, wherein the first nucleic acid segment comprises a plurality of random nucleotides; and the second nucleic acid segment comprises a conserved region common to the plurality of oligonucleotides.

Abstract: The disclosed embodiments generally relate to a method and system to synthesize a target molecule within a droplet. In an exemplary embodiment, a first microfluidic device configured to contact a polynucleotide-containing component from a sample with lysis reagents to form a first droplet. The lysis reagents include an enzyme having protease activity. The first droplet is encapsulated with an immiscible carrier fluid. A collection reservoir is provided to receive and incubate the first droplet for a first duration of time. The first duration of time is sufficient to inactivate the enzyme of the lysis reagent. A second microfluidic device is provided to receive the first droplet and add nucleic acid synthesis reagent to thereby form a second nucleic acid synthesis droplet in the immiscible carrier fluid. Finally, a reaction chamber is provided to synthesize the target polynucleotide within the second nucleic acid synthesis droplet.
