Improve sensitivity for rare targets by increasing total analyzed sample using digital pooling of digital PCR data

For samples with very rare targets, the volume of sample input may impact the ability to detect ultra-rare events. In this technical note, the Digital Pooling feature of the Absolute Q Analysis Software is highlighted by showcasing rare target detection of mutation allele frequencies (MAF) at 0.1% using multiple MAP16 dPCR arrays.
