Abstract:
A device for detecting or quantitating one or more of a plurality of different polynucleotide sequences in a liquid sample, said device comprisinga substrate defining a sample-distribution network having (i) a sample inlet, (ii) two or more detection chambers, and (iii) channel means providing a dead-end fluid connection between each of said chambers and said inlet, wherein at least two of said detection chambers each contain a different, sequence-specific polynucleotide binding polymer for detecting or quantitating different polynucleotide sequences that may be present in such sample, to produce a detectable signal, wherein said substrate comprises two or more laminated layers, whereby evacuation of said network, followed by application of such sample to said inlet, is effective to draw sample by vacuum into each of said chambers.
