Provided is a protein concentration assay method that uses a protein indicating reagent and that enables highly accurate assay. The protein concentration assay method includes: optically analyzing a color exhibited after a sample to be assayed and a protein indicating reagent are brought into contact with each other; measuring pH of the sample to be assayed; and assaying a concentration of protein in the sample based on the result of the optical analysis, the measured value of pH, and data for protein concentration assay, wherein the protein indicating reagent is a protein indicating reagent whose color varies with pH and a concentration of protein, and the data for protein concentration assay include information indicating a way to assay the result of the optical analysis corresponding to the measured value of pH.

Primer sets for amplifying target regions containing sites to be detected in the UGT1A1 gene by a gene amplification method are provided, wherein the primer sets can amplify the regions specifically Three pairs of primer sets are used including forward primers consisting of the base sequences of SEQ ID NOs: 4 or 81, 21, and 42 as well as reverse primers consisting of the base sequences of SEQ ID NOs: 13 or 91, 29 and 48, respectively. The use of these primer sets makes it possible to amplify three target regions including parts where three types of polymorphisms (UGT1A1*6, UGT1A1*27, and UGT1A1*28) of the UGT1A1 gene are generated, respectively, in the same reaction solution at the same time.

Probes for detection of UGT1A1 gene, reagent containing the same, and the uses thereof

Polymorphism detection probes that can distinguish polymorphisms that have only one different base are provided. At least one oligonucleotide selected from the group consisting of the oligonucleotides of SEQ ID NOS. 4, 23, 30, 47, 57 and 64 is used as a probe in a Tm analysis. A Tm analysis using such probes allows easy detection of specific polymorphisms of the FCGR3A gene, the FCGR2A gene, the IL-10 gene, the TNF &#x3b1; gene and the TNF &#x3b2; gene that have an effect on the pharmaceutical effects of antibody drugs or the like. Moreover, such probes allow detection of two or more types of polymorphisms in a single reaction system by introducing two or more types of the probes concomitantly.

An analyzing system that enables further expansion of analysis items and automation of analysis. In the analyzing system for performing an analysis using containerand an analyzing apparatus, containeris a dedicated container previously containing a reagent for a specific analysis item or an expansion container to which a user can freely set an analysis item.

Analyzing system, analyzing apparatus, container, analyzing method, program, and recording medium

Detection probes are provided that are capable of detecting a sequence to be detected containing a mutation even when a sequence not to be detected containing no mutation coexists with the sequence to be detected containing a mutation, which are different only in a single base from each other. At least one oligonucleotide selected from the group consisting of SEQ ID NOs: 2&#x2dc;16 is used as a probe. Even in a sample containing an abl gene in which a mutation has occurred and an abl gene in which no mutation has occurred, the use of such probes in, for example, Tm analysis allows the mutation to be detected.

Primer sets for amplifying two genes (the CYP2C9 gene and the VKORC1 gene) by a gene amplification method are provided, wherein the primer sets can amplify respective target regions of the two genes specifically and efficiently in the same reaction system simultaneously. Two pairs of primer sets are used including forward primers consisting of the base sequences of SEQ ID NOs: 5 and 29 as well as reverse primers consisting of the base sequences of SEQ ID NOs: 18 and 38, respectively. The use of these primer sets makes it possible to specifically amplify target regions including sites where polymorphisms to be detected are generated in the CYP2C9 gene and the VKORC1 gene, in the same reaction solution simultaneously.

A method of producing a PCR amplification product is provided that suppresses an effect of precipitate, turbidity, or the like derived from a whole blood sample on a detection in the detection of an amplified nucleic acid by an optical unit. The amplification product complementary to a target nucleic acid in the whole blood sample is produced by PCR in a condition where a ratio of the whole blood sample in a PCR reaction solution is in the range of 0.1 to 0.9% by volume or 0.01 to 1.8 g/L in term of hemoglobin content. When the PCR is carried out with such conditions, even with an untreated whole blood sample, a monitoring of the amplification product by the optical unit can be done while suppressing the effect of the precipitate or the turbidity.

Primer sets for amplifying target regions containing sites to be detected in the obesity gene (the &#x3b2;2AR gene, the &#x3b2;3AR gene, and the UCP1 gene) by a gene amplification method are provided, wherein the primer sets can amplify the regions specifically. Three pairs of primer sets are used including forward primers composed of the base sequences of SEQ ID NO: 9 or SEQ ID NO: 109, SEQ ID NO: 25, and SEQ ID NO:43 as well as reverse primers composed of the base sequences of SEQ ID NO: 18, SEQ ID NO: 30, and SEQ ID NO: 63, respectively. The use of these primer sets makes it possible to specifically amplify a target region including a site where a polymorphism to be detected is generated in the &#x3b2;2AR gene, the &#x3b2;3AR gene, and the UCP1 gene, in the same reaction solution at the same time.
