Microfluidic device and methods of using same
First Claim
1. A microfluidic device comprising(i) an unbranched serpentine flow channel having a plurality of parallel channel portions in fluid communication with a first fluid inlet and a second fluid inlet, wherein a solution can be introduced into said flow channel via the first fluid inlet and can be withdrawn from said flow channel via the second fluid inlet;
- and(ii) a plurality of valves that, when closed, partition said parallel portions of said flow channel into a series of more than two equally sized isolated reaction sites, said reaction sites being present at a density of at least 50 sites/cm2.

Abstract
A variety of elastomeric-based microfluidic devices and methods for using and manufacturing such devices are provided. Certain of the devices have arrays of reaction sites to facilitate high throughput analyses. Some devices also include reaction sites located at the end of blind channels at which reagents have been previously deposited during manufacture. The reagents become suspended once sample is introduced into the reaction site. The devices can be utilized with a variety of heating devices and thus can be used in a variety of analyses requiring temperature control, including thermocycling applications such as nucleic acid amplification reactions, genotyping and gene expression analyses.
