Abstract

The invention provides methods, apparatus and kits for integrally labeling polymeric gels, such as polyacrylamide and agarose gels, with indicia that can serve, inter alia, unambiguously to identify the individual gel, using polymeric film labeled with detectable indicia and coated with materials that bond to the gel matrix as the gel polymerizes.

Claims

1. An electrophoresis gel cassette comprising:

a label having detectable indicia and a precast electrophoresis gel disposed within the electrophoresis gel cassette, wherein;

i) the label is bonded to an interior surface of the electrophoresis gel cassette and the electrophoresis gel permeates the label, thereby securing the label to the electrophoresis gel;

ii) the indicia are detectable with the label so bonded, and

iii) the label has a smaller surface area than the electrophoresis gel.

2. The electrophoresis gel cassette of claim 1, wherein the indicia are detectable before electrophoresis.

3. The electrophoresis gel cassette of claim 2, wherein the indicia is a barcode.

4. The electrophoresis gel cassette of claim 1, wherein the electrophoresis gel is a polyacrylamide gel.

5. The electrophoresis gel cassette of claim 4, wherein the polyacrylamide is a polymerization product of acrylamide monomer crossliniked with N,N′

-methylenebisacrylamide.

6. The electrophoresis gel cassette of claim 1, wherein the electrophoresis gel is an agarose gel.

7. The electrophoresis gel cassette of claim 6, wherein the agarose gel comprises a natural agarose.

8. The electrophoresis gel cassette of claim 1, wherein the indicia are detectable upon epiillumination.

9. The electrophoresis gel cassette of claim 1, wherein the indicia are detectable upon transillumination.

10. The electrophoresis gel cassette of claim 1, wherein the indicia are capable of fluorescing.

11. The electrophoresis gel cassette of claim 1, wherein the indicia are capable of chemiluminescing.

12. The electrophoresis gel cassette of claim 1, wherein the indicia contain ligands that are capable of binding detectable reagents.

13. The electrophoresis gel cassette of claim 1, wherein the label is a polymeric film.

14. The electrophoresis gel cassette of claim 1, wherein the label is a polymeric film perforated with a uniform density of etched holes.

15. The electrophoresis gel cassette of claim 1, wherein the label has a different shape than said electrophoresis gel.

16. The electrophoresis gel cassette of claim 1, wherein the label is located in a corner of the electrophoresis gel.

17. The electrophoresis gel cassette of claim 1, wherein the label is located in a corner of the electrophoresis gel cassette.

18. The electrophoresis gel cassette of claim 1, wherein the label is reversibly bonded to the interior surface of the electrophoresis gel cassette.

19. The electrophoresis gel cassette of claim 1, wherein the label comprises a list of information regarding the electrophoresis gel cassette.

20. The electrophoresis gel cassette of claim 19, wherein the list of information comprises at least one property of the electrophoresis gel cassette selected from the group consisting of (a) gel composition, (b) pore size, (c) buffer composition, (d) gel pH, (e) pH range of gel (f) date of manufacture, (g) recommended date of expiration, (h) manufacturer name, and (i) catalogue number.

21. The electrophoresis gel cassette of claim 19, wherein the list of information comprises at least two properties of the electrophoresis gel cassette selected from the group consisting of (a) gel composition, (b) pore size, (c) buffer composition, (d) gel pH, (e) pH range of gel (f) date of manufacture, (g) recommended date of expiration, (h) manufacturer name, and (i) catalogue number.

22. The electrophoresis gel cassette of claim 19, wherein the list of information comprises at least three properties of the electrophoresis gel cassette selected from the group consisting of(a) gel composition, (b) pore size, (c) buffer composition, (d) gel pH, (e) pH range of gel (f) date of manufacture, (g) recommended date of expiration, (h) manufacturer name, and (i) catalogue number.

23. The electrophoresis gel cassette of claim 19, wherein the list of information comprises at least four properties of the electrophoresis gel cassette selected from the group consisting of (a) gel composition, (b) pore size, (c) buffer composition, (d) gel pH, (e) pH range of gel (f) date of manufacture, (g) recommended date of expiration, (h) manufacturer name, and (i) catalogue number.

24. The electrophoresis gel cassette of claim 19, wherein the list of information comprises at least six properties of the electrophoresis gel cassette selected from the group consisting of (a) gel composition, (b) pore size, (c) buffer composition, (d) gel pH, (e) pH range of gel (f) date of manufacture, (g) recommended date of expiration, (h) manufacturer name, and (i) catalogue number.

25. The electrophoresis gel cassette of claim 19, wherein the list of information comprises at least nine properties of the electrophoresis gel cassette selected from the group consisting of (a) gel composition, (b) pore size, (c) buffer composition, (d) gel pH, (e) pH range of gel (f) date of manufacture, (g) recommended date of expiration, (h) manufacturer name, and (i) catalogue number.
