Abstract

The present invention relates to, in part, methods, reagents and apparatuses for the detection of agents. The present invention also relates, in part, to compositions including, but not limited to, flow cells, assay chambers, reagent reservoir delivery units and devices for holding an assay chamber. The present invention also provides various components and combinations of components for various detection apparatuses. The present invention also relates to a portable agent detection apparatus that can be used in the field or at a point of care and is not limited to specialized laboratories or limited to use by highly skilled users.

Claims

1. An assay chamber for detecting at least one agent, the assay chamber comprising:

a) a superstructure comprised of a least two circulation ports;

b) a waveguide element comprising at least one binding molecule that binds the at least one agent; and

c) an adhesive means for attaching the base to the waveguide element,

wherein at least one channel is formed between the base and waveguide and wherein the at least two circulation ports and the at least one binding molecule are aligned with the at least one channel.

2. The assay chamber of claim 1, wherein the number of channels is selected from the group consisting of 2, 3, 4, 5, 6, 7, 8, 9 and 10.

3. The assay chamber of claim 1, wherein the base comprises a number of circulation ports selected from the group consisting of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20.

4. The assay chamber of claim 1, further comprising a computer readable label.

5. The assay chamber of claim 1, wherein the waveguide element comprises an opaque mask, wherein the mask is not present in line with at least one situs comprising the at least one binding molecule.

6. The assay chamber of claim 1, wherein the at least one binding molecule comprises a first binding molecule that is capable of binding a first agent and a second binding molecule that is capable of binding a second agent.

7. A method of detecting at least one agent in a sample comprising:

a) contacting the sample or a fraction of the sample with the at least one binding molecule of claim 1;

b) contacting the sample or a fraction of the sample with a detector binding molecule, wherein the detector binding molecule is directly or indirectly associated with a label;

c) detecting a signal from the label; and

d) correlating the detectable signal with the detection of the at least one agent.

8. A method for detecting at least two agents in a sample comprising:

a) contacting the sample or a fraction of the sample with the first and second binding molecules of claim 6;

b) contacting the sample or a fraction of the sample with a first detector binding molecule that is capable of binding a first agent and a second detector binding molecule that is capable of binding a second agent, wherein the first and second detector binding molecules are directly or indirectly associated with a label;

c) detecting a signal from the label; and

d) correlating the detectable signal or signals with the detection of the at least two agents.

9. The method of claim 8 wherein, the first detector binding molecule is labeled with a first label and the second detector binding molecule is labeled with a second label and wherein the first and second label produce distinguishable signals.

10. A method of measuring, detecting or monitoring a binding interaction between the at least one binding molecule and the at least one agent of claim 1 comprising:

a) contacting the at least one agent with the at least one binding molecule, wherein the at least one agent is directly or indirectly labeled;

c) detecting a signal from the label; and

d) correlating the detectable signal with the binding interaction

11. The method of claim 10, wherein the detecting is performed once.

12. The method of claim 10, wherein the detecting is performed at multiple times to produce multiple detectable signals and the multiple detectable signals are correlated with the binding interaction.

13. A device for holding the assay chamber of claim 1 during a detection assay wherein the device allows reagents to circulate through the at least two circulation ports.

14. The device of claim 13, comprising a switch for detecting proper insertion of an assay chamber.

15. The device of claim 13, comprising a clamp mechanism that connects ports in the clamp mechanism to the at least two circulation ports, wherein the connection is made via an O-ring.

16.
