  • Patent number: 9702822
    Abstract: Digital assay system, includes methods, apparatus, and compositions, for distinguishing and measuring different types of templates according to the different lengths of corresponding amplicons, which may be amplified by the same pair of primers. The system may include a length-sensitive reporter generating luminescence that varies according to amplicon length. The system may, for example, be utilized to identify, distinguish, and/or quantify wild-type and mutant/variant templates, processed and unprocessed template, a target template and a primer dimer, or the like.

  • Patent number: 9347094
    Abstract: A method of characterizing telomere length. A template may be synthesized in a bulk phase reaction mixture containing genomic DNA. Partitions may be formed after synthesizing the template in the bulk phase reaction mixture, with only a subset of the partitions containing at least one copy of the template. At least a region of the template may be amplified in partitions. Amplification data may be collected from partitions. A measure of telomere length may be determined for the genomic DNA based on the amplification data. In some embodiments, the bulk phase reaction mixture may be thermally cycled for at least two cycles, and heated to a denaturation temperature and cooled to an annealing temperature in each cycle.
