DdRFC: A scalable multiplexed droplet digital nucleic acid amplification test platform.

ABSTRACT: Digital nucleic acid amplification tests (digital NAATs) have emerged as a popular tool for nucleic acid detection due to their high sensitivity and specificity. Most current digital NAAT platforms, however, are limited to a "one-color-one-target" approach wherein each target is encoded with a specific fluorescently-labeled probe for single-plex fluorometric detection. This approach is difficult to multiplex due to spectral overlap between any additional fluorophores, and multiplexability of digital NAATs has therefore been limited. As a means to scale multiplexability, we have developed a multiplexed digital NAAT platform, termed Droplet Digital Ratiometric Fluorescence Coding (ddRFC), via a padlock probe-based nucleic acid detection assay which encodes each nucleic acid target with a uni
