- 13. The DNA capillary according to claim 1, wherein said DNA probe comprises at least 20 bases.
- 14. The DNA capillary according to claim 2, wherein said DNA probe comprises at least 20 bases.
- 15. The DNA capillary according to claim 1, wherein adjacent open portions are arranged deviant from each other in the fluid flowing direction, and the processing regions of all the fluid passageways are equal to each other in the length in the fluid flowing direction and the both ends of the processing regions are aligned.
- 16. The DNA capillary according to claim 2, wherein adjacent open portions are arranged deviant from each other in the fluid flowing direction, and the processing regions of all the fluid passageways are equal to each other in the length in the fluid flowing direction and the both ends of the processing regions are aligned.
- 17. The DNA capillary according to claim 1, wherein the cross sectional shape of the fluid passageway includes a curved portion.
- 18. The DNA capillary according to claim 2, wherein the cross sectional shape of the fluid passageway includes a curved portion.
