Abstract: The present disclosure provides a measurement method of telomerase activity with no occurrence of false-negative and high quantitative capability. In the measurement method of telomerase activity of the present disclosure, a solution containing telomerase as a sample solution is mixed with a solution containing primer DNA as a substrate for telomerase even as or after a solution containing non-primer DNA not as a substrate for telomerase is mixed therewith. Non-primer DNA can remove an effect of DNase in the sample solution and prevent occurrence of false-negative. Subsequently, the primer DNA is extended with the telomerase and the extended primer DNA is detected, through which telomerase activity is measured.

Abstract: The present invention provides a method for determining whether or not a capillary filled with an electrophoretic medium is suitably used for electrophoresis before electrophoresis is performed using the analytes. The method comprises (a) applying an alternating-current voltage between a first electrode which is in contact with a first electrolyte solution in which one end of the capillary is immersed and a second electrode which is in contact with a second electrolyte solution in which the other end of the capillary is immersed to measure an electric conductivity of the electrophoresis medium with which an inside of the capillary is filled; and (b) determining that the capillary filled with the electrophoresis medium fails to be used suitably for the electrophoresis, when the electric conductivity is more than 4.2 mS/cm.

Abstract: the present invention provides an amplification method capable of inhibiting the generating of the undesired amplified double-stranded DNA sequence. In the present method, DNA polymerase, deoxynucleoside triphosphate, the double-stranded DNA, a forward primer, a reverse primer, and a first block nucleic acid are mixed so as to amplify the double-stranded target sequence with use of a polymerase chain reaction. The first block nucleic acid does not serve as an origin for the elongation reaction with the DNA polymerase. The first block nucleic acid is complementary with a part of the third non-amplified sequence which is interposed between the 5? end and the complimentary single-stranded target sequence. Due to the first block nucleic acid, the generating of the undesired amplified double-stranded DNA sequence is inhibited.

Abstract: A liquid delivery apparatus 1 has a rotary substrate 2. The substrate 2 formed with a fluid passage 8A for communicating a supply chamber 6A and target chamber 7A. An inlet end portion 13 at which the fluid passage 8A is connected to the chamber 6A extends in a clockwise direction R1 of rotational directions of the substrate 2. The inlet end portion 13 holds a liquid 9 in the chamber 6A by a capillary force. The rotation drive unit 4 rotates the substrate 2 so that an inertial force exceeding the capillary force and directed to the clockwise direction R1 acts on the liquid 9 in the inlet end portion 13. Delivery behavior control of microfluid with a high degree of flexibility can be achieved.
