摘要:
A process for producing a test piece for analyzing a labeled substance with a biological origin which comprises the step of supplying a solution containing a substance capable of specifically binding to the substance with the biological origin onto a support and fixing the specifically binding substance at a definite position on the support, characterized in that the solution contains a substance to be detected, which is either the same as the label or different therefrom, uniformly dissolved or dispersed therein independently from the specifically binding substance. A method of examining a test piece having a substance specifically binding to a substance with a biological origin fixed at a definite position on a support, characterized by comprising the step of supplying a labeled test substance onto a support and fixing it at a position different from the position of the specifically binding substance, and the step of eliminating the unfixed test substance.

A reaction vessel includes a three-dimensional substrate on which a probe applied to detection of a biorelated substance is immobilized, a coupling portion allowed to be coupled to a liquid driver in an airtight fashion, and a solution sucking portion allowed to suck a solution. The coupling portion and the solution sucking portion are arranged with a three-dimensional substrate held between them.

An object of the invention is to provide a quick, easy, and highly-sensitive method of detecting a substance to be analyzed, and to provide a method of supporting the analysis results by quantitativeness even if the amount of samples to be handled is a very small amount. The invention is a method of detecting a substance to be analyzed, including: measuring a intensity of a signal derived from a labeled substance to be analyzed, in a time series during an increase in the signal intensity; and representing the signal intensity by a function of time, and using the quantitative value of the signal intensity for when the slope of an approximated line of the measured signal intensity is within a range between 0.5 and 1.5 times the slope of the approximated line of the previously measured signal intensity.

That invention provides a nucleic acid information detection method which, in a method wherein a target nucleic acid, and probes having a complementary sequence with at least a portion of the target nucleic acid sequence, are contacted with each other in order to form hybrids between the target nucleic acid and the probes, and the amount of signal generated depending on the amount of hybrids is measured in order to detect the information on the target nucleic acid, includes kinetically obtaining data of the signal. Furthermore the invention provides a nucleic acid information detection method which, in a method wherein a perfect matched probe having a perfect complementary sequence with respect to at least part of a target nucleic acid sequence, and one or more types of imperfectly matched probes having at least one part of the perfect matched probe mutated, are contacted with the target nucleic acid in order to hybridize between the target nucleic acid and the perfect matched probe, or the imperfect matched probes, so that the information on the target nucleic acid can be detected based on the difference in binding strength of the hybrids, includes kinetically obtaining data of the signal while changing continuously or stepwise the condition for measuring or detecting the signal from the hybrids.

A sample container containing a biopsy sample obtained by an instrument is arranged in the operation section of an endoscope. The sampling means of an instrument inserted into the subject through the instrument channel of the endoscope is used, obtaining a biopsy sample. The biopsy sample is introduced from the instrument into the sample container arranged in the operation section, without pulling the instrument outside. The sample obtained can therefore be stabilized fast and be preserved fresh. The biopsy sample is prevented from being contaminated and from contaminating the environment. The sample can therefore undergo accurate examinations and diagnoses.

In a method of making a high-quality silica glass, a rare earth element that is a substance making a great contribution to the index of refraction is introduced therein together with aluminum for stabilizing the glass. An alkoxide of aluminum or its derivative is used as the starting material for preparing a boehmite sol. A salt of at least one element selected from rare earth elements or a solution in which the salt is dissolved and the boehmite sol are mixed with a silica sol, whereupon the sols are vitrified.
