Abstract:
The present invention generally relates to droplet libraries and to systems and methods for the formation of libraries of droplets. The present invention also relates to methods utilizing these droplet libraries in various biological, chemical, or diagnostic assays.
Abstract:
In certain aspects, methods of the invention involve performing modification state specific enzymatic reaction of nucleic acid in a sample, determining a value associated with efficiency of the modification state specific enzymatic reaction based on a control, determining an amount of target nucleic acid in the sample, and normalizing the amount of target nucleic acid based on the efficiency value. Based on the normalized amount of target nucleic acid, the method further includes determining whether the normalized amount of target nucleic acid is indicative of a condition.
Abstract:
The invention generally relates to methods for increasing the amount of DNA available for analysis when using partitioned samples and parallel processing. For example, double-stranded DNA can be dissociated into two single-stranded components, and the single strands partitioned into different droplets prior to analysis. The disclosed methods are useful for performing digital PCR analysis on samples where the target DNA is not in abundance, for example when the sample originates from a body fluid or an FFPE sample.
Abstract:
The invention provides barcode libraries and methods of making and using them including obtaining a plurality of nucleic acid constructs in which each construct comprises a unique N-mer and a functional N-mer and segregating the constructs into a fluid compartments such that each compartment contains one or more copies of a unique construct. The invention further provides methods for digital PCR and for use of barcode libraries in digital PCR.

Abstract:
The invention includes methods for determining the presence of a latent viral population by analyzing an RNA population from the virus with digital techniques, such as digital PCR or by sequencing cDNA produced from the RNA. The invention additional includes methods for determining the presence of latent viral populations by detecting and/or quantifying enzymes that are uniquely associated with the virus, e.g., reverse transcriptases.
Abstract:
The invention generally relates to method for screening for a condition in a subject. In certain embodiments, methods of the invention involve obtaining a pool of nucleic acids from a sample, incubating the nucleic acids with first and second sets of binders, in which the first set binds uniquely to different regions of a target nucleic acid in the pool, the second set binds uniquely to different regions of a reference nucleic acid in the pool, and the first and second sets include different detectable labels, removing unbound binders, detecting the labels, and screening for a condition based upon results of the detecting step.
