Embodiment Construction

[0055] Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

[0056] Figure 1 ~ Figure 3 shows the analysis tool according to the first embodiment of the present invention, Figure 4 An analysis system according to the first embodiment of the present invention is shown. The analysis system C of the present embodiment is configured to include an analysis device B and an analysis tool A1. The analysis system C is a system that executes an analysis method based on the electrophoresis method targeting a sample. The sample is not particularly limited, but in this embodiment, blood collected from a human body will be described as an example. Among the components contained in the sample, a component to be analyzed is defined as an analysis component.

[0057]Examples of the analysis components include hemoglobin (Hb), albumin (Alb), globulin (α1, α2, β, γ globulin), fibrinogen, and the like. Examples of the h...

Abstract

The present invention provides an analysis tool and an analysis system capable of appropriately removing analysis hindering factors and performing more stable analysis. An analysis tool (A1) used for analysis of samples based on capillary electrophoresis, comprising: an introduction tank (2) for introducing the sample; a capillary (4) connected to the introduction tank (2); a filter component (21), for the passage of the sample introduced into the introduction tank (2); the sharply enlarged part (61), which is connected with the introduction tank (2) and the capillary tube (4), has a sharply enlarged cross-sectional area; The body (81) suppresses the pressure change caused by the surface tension of the liquid that would occur in the rapidly expanding portion (61) from acting on the liquid in the capillary (4).

Description

technical field [0001] The invention relates to an analysis tool and an analysis system. Background technique [0002] Glycation rates of various proteins were analyzed as indicators showing the state of the living body. In particular, the glycation rate of hemoglobin (Hb) in blood cells, especially the stable HbA1c (hereinafter sometimes abbreviated as "s-HbA1c") reflects the past history of the blood sugar level in the living body, so it is used in the diagnosis and treatment of diabetes, etc. important indicators. HbA1c is a glycated product of valine at the N-terminal of the β chain of HbA (α2β2). [0003] As one of methods for analyzing Hb represented by s-HbA1c, electrophoresis is used. Patent Documents 1, 2, 3, 4, and 5 disclose adding additional components to the electrophoretic solution for the purpose of rationalization of analysis and improvement of precision. In particular, Patent Documents 4 and 5 disclose chondroitin sulfate as an example of an additive com...
