Single molecule-based protocols have been gaining popularity as a way to visualize DNA replication at the global genomic and locus-specific levels. These protocols take advantage of the ability of many organisms to incorporate nucleoside analogs during DNA replication, together with a method for displaying stretched DNA on glass for immunostaining and microscopy. We describe here a microfluidic platform that can be used to stretch and capture labeled DNA molecules for replication analyses. This platform consists of parallel arrays of 3-sided, 3 or 4 μm high, variable width capillary channels fabricated from polymethyl siloxane (PDMS) by conventional soft lithography, and silane-modified glass coverslips to reversibly seal the open side of the channels. Capillary tension in these microchannels facilitates DNA loading, stretching and glass coverslip deposition from μL-scale DNA samples. The simplicity and extensibility of this platform should facilitate DNA replication analyses using small samples from a variety of biological and clinical sources.
