Abstract:
The present invention relates to a device for injecting and extracting accurately infinitesimal amount of sample according to a magnitude of volage and a direction of current applied to a device for generating an electroosmotic flow by coupling ultra-micro capillaries for injecting and extracting the sample with an electroosmotic flow generating device in which an electrical circuit is completed through an electroconductive membrane, and a method for manufacturing the same. The device according to the present invention is invented for injecting and extracting accurately infinitesimal amount of sample for the single cell as the object, however, the present invention can be applied to all the other fields in which infinitesimal amount of sample should be accurately treated. As compared with the conventional air pressure type or mechanical pumping method having various problems due to an extreme resistance to the fluid flowed through the ultra-micro capillary, in the electroosmotic flow-type device, a driving force is generated on a surface of inner wall of the capillary so that there is no a resistance in the capillary although the fluid is flowed therein. Also, since a regulation of the driving force is achived by an accurate and simple regulation of the voltage, a flow of infinitesimal amount of fluid can be accurately controlled. In the present invention, the capillary for generating the electroosmotic flow is directly coupled with the capillary for extracting the sample through the electroconductive tube, the electroosmotic flow-type ultra-micro pipet divce in which a dead volume generated at a coupling section is minimized can be conveniently manufactured and employed.

Abstract:
The present invention is related to a method of separation of compounds by electrophoresis in which the compounds such as genes, proteins, etc. may be analyzed very precisely as samples are introduced directly into the separation tubes of the chip at the collection site, and therefore, it is not necessary to have separate fluid paths or individual sample storing apparatus that have been necessary for the conventional electrophoresis; it is easy to make the chip as the structure of the chip becomes extremely simple, and high-density arrangement of the separation tubes is enabled; and further, the compounds such as genes, proteins, etc. may be analyzed very precisely without interference in the storage tubs by using a non-polar solvent as the solvent of the sample storage tub.
Abstract:
Disclosed herein is a method for screening a probe set for detecting a target gene using a FRET system, the method comprising the steps of: (A) determining one common primer to a complementary strand from the base sequence of a target gene and designing a plurality of different primers to a target strand; (B) mixing the primers with DNA containing the target gene and subjecting the mixtures to PCR so as to first screen primers to the target strand, which produce products; (C) mixing the first screened primers with one common primer to the com¬ plementary strand and DNA containing no target gene, subjecting the mixtures to PCR so as to second screen primers to the target strand, which produce no product; and (D) selecting any two primers from the group consisting of the second screened primers to the target strand and labeling the selected primers with an energy donor and energy acceptor for FRET test, re¬ spectively. The use of the method not only allows the reduction of enormous expense required for a gene labeling process but also can increase the accuracy and selectivity of a probe set to a target gene so as to perform a target gene detection process in a more rapid and easy manner.
