Sample plate systems and methods
A sample plate comprising a sample well is disclosed. The sample well can comprise one or more bead retaining chambers. A method of using the sample plate and a kit comprising the sample plate is also disclosed.
1. A sample plate comprising:
at least one sample well including:
a base portion;
a plurality of recesses provided in said base portion; and
a plurality of beads received in said plurality of recesses, wherein each of said plurality of beads is retained or secured within a respective one of said plurality of recesses to substantially fluid-tightly seal the base portion at said plurality of recesses.
2. The sample plate of claim 1 , wherein each of the plurality of recesses is defined, at least in part, by a respective wall of said base portion and each of said plurality of beads forms a substantially fluid-tight circumferential seal around the respective wall of said base portion.
3. The sample plate of claim 1 , wherein said plurality of recesses constitute blind recesses formed in said base portion.
4. The sample plate of claim 1 , wherein said plurality of recesses constitute open through holes formed in said base portion.
5. The sample plate of claim 1 , wherein each of said plurality of recesses is substantially cylindrical.
6. The sample plate of claim 1 , wherein each of said plurality of recesses is conical and has a first diameter which is greater than a diameter of a respective one of said plurality of beads deposited in said each of said plurality of recesses and a second diameter which is less than the diameter of said respective one of said plurality of beads.
7. The sample plate of claim 1 , wherein said plurality of recesses are arranged circumferentially around a central portion of said sample well.
8. The sample plate of claim 1 , wherein said base portion is segmented into a plurality of segments which are arranged at different heights relative to each other.
9. A sample plate comprising:
at least one sample well including:
a base portion, wherein said base portion is segmented into a plurality of segments which are arranged at different heights relative to each other;
a plurality of recesses provided in said base portion; and
a plurality of beads received in said plurality of recesses.
10. The sample plate of claim 1 , wherein said at least one sample well further comprises one or more baffles or dividers which separates or divides said base portion into at least a first region and a second region.
11. The sample plate of claim 10 , wherein said one or more baffles or dividers attenuate or eliminate light reflected off certain ones of said plurality of beads which are located in said first region from impinging upon other ones of said plurality reagent beads located in said second region.
12. The sample plate of claim 1 , wherein at least some of said plurality of recesses comprise a countersunk portion.
13. A sample well comprising:
a base portion;
a plurality of recesses provided in said base portion; and
a plurality of beads received in said plurality of recesses, wherein each of said plurality of beads is retained or secured within a respective one of said plurality of recesses to substantially fluid-tightly seal the base portion at said plurality of recesses.
14. The sample well of claim 13 , wherein each of the plurality of recesses is defined, at least in part, by a respective wall of said base portion and each of said plurality of beads forms a substantially fluid-tight circumferential seal around the respective wall of said base portion.
15. The sample well of claim 13 , wherein said plurality of recesses constitute blind recesses formed in said base portion.
16. The sample well of claim 13 , wherein said plurality of recesses constitute open through holes formed in said base portion.
17. The sample well of claim 13 , wherein each of said plurality of recesses is substantially cylindrical.
18. The sample well of claim 13 , wherein each of said plurality of recesses is conical and has a first diameter which is greater than a diameter of a respective one of said plurality of beads deposited in said each of said plurality of recesses and a second diameter which is less than the diameter of said respective one of said plurality of beads.
19. The sample well of claim 13 , wherein said plurality of recesses are arranged circumferentially around a central portion of said sample well.
20. The sample well of claim 13 , wherein said base portion is segmented into a plurality of segments which are arranged at different heights relative to each other.
