Abstract
Abstract The invention is directed to a method and device for simultaneously testing a sample for the presence, absence, and/or amounts of one or more a plurality of selected analytes. The invention includes, in one aspect, a device for detecting or quantitating a plurality of different analytes in a liquid sample. The device includes a substrate which defines a sample-distribution network having (i) a sample inlet, (ii) one or more detection chambers, and (iii) channel means providing a dead-end fluid connection between each of the chambers and the inlet. Each chamber may include an analyte-specific reagent effective to react with a selected analyte that may be present in the sample, and detection means for detecting the signal. Also disclosed are methods utilizing the device.

Claim 1
Independent Claim
119 words
A device for detecting or quantitating one or more of a plurality of different polynucleotide sequences in a liquid sample, said device comprising a 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, whereby evacuation of said network, followed by application of such sample to said inlet, is effective to draw such sample by vacuum into each of said chambers.
