DNA-Binding Magnetic Nanoreactor Beads for Digital PCR Analysis.

ABSTRACT: Digital PCR (dPCR) is based on the separation of target amplification reactions into many compartments with randomly distributed template molecules. Here, we present a novel digital PCR format based on DNA binding magnetic nanoreactor beads (mNRBs). Our approach relies on the binding of all nucleic acids present in a sample to the mNRBs, which both provide a high-capacity binding matrix for capturing nucleic acids from a sample and define the space available for PCR amplification by the internal volume of their hydrogel core. Unlike conventional dPCR, this approach does not require a precise determination of the volume of the compartments used but only their number to calculate the number of amplified targets. We present a procedure in which genomic DNA is bound, the nanoreactors are loade
