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.

Claims

providing a device comprising a substrate defining a sample-distribution network including (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 pre-loaded therein, at least one 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,

applying the sample to the sample inlet and delivering the sample into the network by action of a force whereby the sample is delivered to the detection chambers,

allowing the delivered sample to react with the at least one different, sequence-specific polynucleotide binding polymer in each detection chamber under conditions effective to produce a detectable signal in each detection chamber when the one or more polynucleotide sequences are present in the sample, and

measuring the detectable signal to detect or quantitate the one or more polynucleotide sequences in the sample.

2. The method of claim 1, wherein said channel means comprises a single channel to which said detection chambers are connected by said fluid connections.

3. The method of claim 1, wherein said channel means comprises a first channel to which a first group of detection chambers are connected by such fluid connections, and a second channel to which a second group of detection chambers are connected.

4. The method of claim 1, wherein said channel means comprises an individual channel for each detection chamber, for providing a dead-end fluid connection between said sample inlet and each detection chamber.

5. The method of claim 1, wherein said device further comprises a port connected to the channel means at a site in fluid communication with the sample inlet and detection chambers.

6. The method of claim 5, wherein said port is connected to the channel means at a site that is downstream of said sample inlet and said detection chambers.

7. The method of claim 1, wherein said device further comprises a non-flowthrough reservoir in fluid communication with said channel means.

8. The method of claim 1, wherein the at least one different, sequence-specific polynucleotide binding polymer comprises an oligonucleotide primer pair suitable for amplifying, by polymerase chain reaction, a specific polynucleotide sequence which is flanked by sequences complementary to the primer pair.
