Abstract
The hybridization reactions of DNA with peptide nucleic acids (PNA) were monitored in real time with Temperature Gradient Focusing (TGF). Both ex situ and in situ reactions of a perfect complement and mismatched ssDNA targets with PNA were monitored by fluorescence microscopy. TGF was used to first spatially focus a plug of ssDNA within a microchannel and then to hold the plug stationary for hybridization with a peptide nucleic acid probe transported by bulk flow of the buffer. The mismatched ssDNA target did not react with the PNA. TGF of PNA/DNA demonstrated a 500-fold increase in concentration during a 20 minute experiment.Citation
