    Abstract: The present methods are exemplified by a process in which maternal blood containing fetal DNA is diluted to a nominal value of approximately 0.5 genome equivalent of DNA per reaction sample. Digital PCR is then be used to detect aneuploidy, such as the trisomy that causes Down Syndrome. Since aneuploidies do not present a mutational change in sequence, and are merely a change in the number of chromosomes, it has not been possible to detect them in a fetus without resorting to invasive techniques such as amniocentesis or chorionic villi sampling. Digital amplification allows the detection of aneuploidy using massively parallel amplification and detection methods, examining, e.g., 10,000 genome equivalents.

    Abstract: The present invention features methods for analyzing a sequence of a target polynucleotide by detecting incorporation of a nucleotide into its complementary strand, where the polynucleotides may be bound at high density and at single molecule resolution. The invention also features labeling moieties and blocking moieties, which facilitate chain termination or choking. Certain aspects provide for temporal detection of the incorporations; some allow for asynchronous analysis of a plurality of target polynucleotides and the use of short sequencing cycles. Surface chemistry aspects of the sequencing methods are also provided. The method may also be used in kits, said kits designed to carry out and facilitate the methods provided herein.
