Patent ID: 8591834

Claim:
A microfluidic device comprising an array of fluidically interconnected unit cells, wherein each unit cell comprises: a) a first microfluidic flow path in fluid communication with: 1) a reaction chamber, and 2) a first microfluidic bus line, wherein said first microfluidic bus line is in fluidic communication with a sample source reservoir; b) a first valve situated in said first microfluidic flow path; c) a second valve situated in said first microfluidic flow path; d) a second microfluidic flow path in fluidic communication with: 1) said first microfluidic flow path at a junction between said first and second valves, and 2) a second microfluidic bus line, wherein said second microfluidic bus line is in fluidic communication with a reagent source reservoir e) a third valve situated 1) in said second microfluidic flow path, or 2) in said second microfluidic bus line positioned between the second microfluidic flow path of said unit cell and the second microfluidic flow path of an adjacent unit cell.
