Abstract:
The present invention provides methods for selectively enriching a biological sample for short nucleic acids, such as fetal DNA in a maternal sample or apoptic DNA in a biological sample from a cancer patient and for subsequently analyzing the short nucleic acids for genotype, mutation, and/or aneuploidy.
Abstract:
The present invention provides amplification-based methods for detection of genotype, mutations, and/or aneuploidy. These methods have broad applicability, but are particularly well-suited to detecting and quantifying target nucleic acids in free fetal DNA present in a maternal bodily fluid sample.
Abstract:
The present invention provides for determining relative copy number difference for one or more target nucleic acid sequences between a test sample and a reference sample or reference value derived therefrom. The methods facilitate the detection of copy number differences less than 1.5-fold.

Abstract:
The present invention provides methods for analysis of genomic DNA and/or RNA from small samples or even single cells. Methods for analyzing genomic DNA can entail whole genome amplification (WGA), followed by preamplification and amplification of selected target nucleic acids. Methods for analyzing RNA can entail reverse transcription of the desired RNA, followed by preamplification and amplification of selected target nucleic acids.
Abstract:
The present invention provides assay methods that increase the number of samples and/or target nucleic acids that can be analyzed in a single assay.
Abstract:
The present disclosure relates to methods for detecting a plurality of target nucleic acids in a plurality of samples comprising providing S samples that will be mixed together prior to assay, where S is an integer greater than 1; separately subjecting each of said S samples to an encoding reaction that produces a set of T tagged target nucleotide sequences, each tagged target nucleotide sequence comprising a sample-specific nucleotide tag and a target nucleotide sequence; wherein T is the number of target nucleic acids to be detected, T being an integer greater than one; mixing together tagged target nucleotide sequences from said S samples to form an assay mixture; dividing the assay mixture into up to S × T amplification mixtures, and separately subjecting each of said amplification mixtures to amplification using a unique pair of amplification primers.
