Background: Accurate methods to assess DNA integrity are needed for many biomolecular methods. A multiplex digital PCR (dPCR) method designed for interspaced target sequences can be used to assess sequence integrity of large DNA strands. The ratio of single positive partitions versus double positive partitions is then used to calculate the sheared DNA strands. However, this simple calculation is only valid with low DNA concentration. We here describe a method based on probability calculations which enables DNA quality analysis in a large dynamic range of DNA concentrations. Results: Known DNA ...
