Abstract
The present invention relates to, inter alia, a microfluidic device for performing single cell genomic DNA isolation and amplification under flow. The microfluidic device comprises a solid substrate having one or more microfluidic channel system formed therein. Each microfluidic channel system of the microfluidic device comprises: (a) an intake region comprising a single microchannel; (b) a plurality of cell segregation microchannels; (c) a cell capture site located downstream of each cell segregation microchannel; and (d) a DNA capture array positioned downstream of the cell capture site and comprising a plurality of micropillars. Also disclosed is a whole genome amplification system that includes the microfluidic device of the present disclosure, as well as a method for conducting single cell DNA analysis via on-chip whole genome amplification while under flow, and a method for multiple displacement amplification (MDA) reactions of one or more nucleic acid sequence isolated single cells.
