Device for detection of analytes and uses thereof
Devices and methods for the detection of antigens are disclosed. Devices and methods for detecting food-borne pathogens are disclosed.
1. A device for detecting an analyte comprising a first outer member and a second outer member comprising:
a conjugate pad,
a first inner member and a second inner member,
wherein the first inner member and second inner member are in contact with each other,
wherein said first outer member and first inner member comprise an inlet, wherein the inlet is in fluid contact with the conjugate pad, and
wherein between the first and second inner members is an analyte detection membrane system comprising in the following order:
a test membrane; and
an absorbent member; and
wherein at least a portion of each of the conjugate pad, test membrane, and absorbent member are substantially parallel to each other, and
wherein said analyte detection membrane system is compressed between the first inner member and second inner member, and
wherein said conjugate pad is not compressed between said first and second inner members.
2. The device of claim 1 , wherein said first outer member comprises a layer that can be removed or moved to expose the conjugate pad.
3. The device of claim 2 , wherein said conjugate pad is attached to said removable or movable layer.
4. The device of claim 1 , wherein said conjugate pad is attached to said first outer member.
5. The device of claim 1 , wherein said conjugate pad is a glass fiber conjugate pad.
6. The device of claim 1 , wherein said first outer member and second outer member form a container.
7. The device of claim 6 , wherein said container comprises a removable or movable layer.
8. The device of claim 7 , wherein said removable or movable layer is for removing or moving the conjugate pad.
9. The device of claim 6 , wherein a first surface of the conjugate pad is in contact with the first outer member and a second surface of the conjugate pad is in contact with the first inner member.
10. The device of claim 1 , wherein said first inner member and said second inner member are attached to one another along an edge of the first member that is parallel to an edge of the second member.
11. The device of claim 1 , wherein said first inner member and second inner member are attached to each other with a spring or hinge.
12. A system comprising a device of claim 1 and a buffer container or a sample collector.
13. A kit comprising the device of claim 1 and one or more of a positive control, a negative control, an instruction booklet, a buffer container, and a sample collector, or any combination thereof.
14. The device of claim 1 , wherein said conjugate pad further comprises a tab.
