Abstract: A method for detecting amplified nucleic acid fragments is provided. The method comprises the steps of carrying out amplification reaction to amplify a predetermined region of a nucleic acid in a reaction solution comprising the nucleic acid as a template, a pair of primers, deoxynucleotides, and dideoxynucleotides; hybridizing the amplified products of the reaction solution to a probe; and then detecting the hybridization between the amplified products and the probe.

Abstract: A method for detecting amplified nucleic acid fragments with high accuracy is provided. The method comprises the steps of carrying out amplification reaction to amplify a predetermined region of a nucleic acid in a reaction solution comprising the nucleic acid as a template, a pair of primers, deoxynucleotides, and deoxynucleotides; hybridizing the amplified products comprised in the reaction solution to a probe; and then detecting the hybridization between the amplified products and the probe.

Abstract: In order to specifically and high-sensitively measure multiple antibodies, an antibody detector utilizes the specificity of an antigen-antibody reaction. The antibody detector comprises a plurality of polypeptide units, each of which is partly or entirely epitope, that are connected, with or without a spacer, and that are immobilized on a carrier.

Abstract: A spotting pin 10 capable of spotting equal amounts of a solution in a sequential manner comprises a first member 11 having a solution holding portion 13 formed at the tip thereof for holding a predetermined amount of solution, and a second member 12 having a solution supply portion 14 for holding the solution by a capillary action, the second member adapted to slide along the first member. As the solution supply portion 14 is brought into contact with the solution holding portion 13, the solution enters the solution holding portion 13 from the solution supply portion 14 by a capillary action. As the solution supply portion 14 and the solution holding portion 13 are separated from each other, a predetermined amount of the solution can be carried in the solution holding portion 13. Then, as the solution holding portion 13 is brought into contact with a water-absorbing support 21, a spot 22 of a predetermined amount of the solution can be formed thereon.

Abstract: Identically shaped spots can be formed sequentially and stably by a spotting pin comprising a bar-like plunger 20. Four projections each formed in the shape of a top portion of a quadrangular pyramid are formed on the head of the plunger 20. The apexes 21 of the quadrangular pyramids constituting the projections are located inside a virtual plane extending from the peripheral wall of the plunger.
