Devices and methods for biological assay sample preparation and delivery
Devices and methods for preparing and delivering biological assay samples are provided herein. Components of such devices include a sample receiving module within which a biological assay sample can be prepared and a cap, which when operatively coupled with the sample receiving module, pressurizes the module. These devices can be employed for subsequently delivering a biological assay sample.
1. A method of delivering a biological assay sample, the method comprising:
a. collecting a biological sample with a sample collector;
b. inserting the sample collector into a sample receiving module of a sample preparation device, wherein inserting the sample collector comprises exposing the biological sample to a preparation solution to produce a prepared biological assay sample, wherein the sample receiving module comprises an outer body forming a first chamber, an inner body forming a second chamber, and a first attachment element, wherein the outer body comprises a piercing member, and wherein the inner body comprises a breakable seal and is movable within the outer body;
c. operatively coupling a cap of the sample preparation device to the sample receiving module and thereby pressurizing the prepared biological assay sample within the sample receiving module, wherein the cap comprises a second attachment element operatively coupleable with the first attachment element and wherein operatively coupling the cap comprises moving the inner body within the outer body to break the breakable seal and place the first and second chambers in fluidic communication; and
d. depressurizing the prepared biological assay sample within the sample receiving module by flowing at least a portion of the prepared biological assay sample out of the sample receiving module.
2. The method according to claim 1 , wherein the preparation solution comprises a nucleic acid preparation solution.
3. The method according to claim 1 , wherein the preparation solution is a nucleic acid amplification preparation solution.
4. The method according to claim 3 , wherein the prepared sample comprises a prepared nucleic acid amplification sample.
5. The method according to claim 1 , wherein the prepared sample is a prepared nucleic acid amplification sample.
6. The method according to claim 1 , wherein the cap comprises a pressurizing component and operatively coupling the cap comprises inserting the pressurizing component into the sample receiving module.
7. The method according to claim 1 , wherein operatively coupling the cap of the sample preparation device to the sample receiving module comprises inserting an end of the sample receiving module into the cap.
8. The method according to claim 1 , wherein operatively coupling the cap of the sample preparation device to the sample receiving module comprises screwing the sample receiving module to the cap.
9. The method according to claim 1 , wherein pressurizing the sample receiving module comprises pressurizing the module to a peak pressure ranging from 10,000 Pa to 30,000 Pa.
10. The method according to claim 1 , wherein the sample receiving module is shaped as a cylinder having a diameter of 5 cm or less and having a height of 20 cm or less.
11. The method according to claim 1 , wherein the sample receiving module has a volume ranging from 1 cm 3 to 50 cm 3 .
12. The method according to claim 1 , wherein the cap is operatively coupled to a first end of the sample preparation device and an actuable valve is at a second end of the sample preparation device opposite the first end.
13. The method according to claim 1 , wherein the device further comprises a filter and the method further comprises filtering a sample fluid with the filter prior to discharging sample fluid.
14. The method according to claim 1 , wherein the outer body comprises a staging reagent and wherein placing the first and second chambers in fluidic communication comprises mixing the prepared biological assay sample and the staging reagent.
15. The method according to claim 1 , wherein operatively coupling the cap of the sample preparation device to the sample receiving module comprises mateably connecting the first and second attachment elements.
16. The method according to claim 1 , wherein the sample receiving module further comprises a second breakable seal over an opening and wherein inserting the sample collector into the sample receiving module of the sample preparation device comprises breaking the second breakable seal and inserting at least a portion of the sample collector through the opening.
17. The method according to claim 1 , further comprising delivering one or more heating reagents into the sample receiving module which, when delivered, cause an exothermal reaction and heat the biological sample.
18. The method according to claim 1 , further comprising delivering one or more gas-producing reagents into the sample receiving module which, when delivered, generate a gas.
19. The method according to claim 1 , wherein the device further comprises a filter and the method comprises concentrating one or more particles of the biological sample by flowing at least a portion of the prepared biological assay sample through the filter.
20. The method according to claim 1 , wherein the sample receiving module further comprises an actuable valve.
21. The method according to claim 20 , wherein flowing at least a portion of the prepared biological assay sample out of the sample receiving module comprises flowing the prepared biological assay sample through the actuable valve.
22. The method of claim 14 , wherein the staging reagent is a lyophilized lysing reagent.
