Abstract: To provide a reagent applying device and a reagent applying method for electrophoresis analysis which make it possible to apply a reagent with a simple configuration at low cost. A reagent supplying device for supplying a reagent to the surface of a gel in electrophoresis analysis includes a reagent applying tool which is a plate-shaped body. The reagent applying tool includes at least one reagent holding section which penetrates the reagent applying tool in a thickness direction and which holds a reagent by capillary action, and a reagent spreading section for spreading, on the surface of the gel, a reagent supplied from a lower-side opening of the reagent holding section when the reagent applying tool is placed on the gel.

Abstract: A method for separating and assaying lipoprotain to determine a degree of modification of a predetermined component in a specimen of lipoprotein, comprising the step of: determining a distance “a” from an application point of the standard sample to a fraction corresponding to the predetermined lipoprotein using an electrophoretic pattern obtained by electrophoresis of a standard sample; determining a distance “b” from the application point of the specimen to a fraction corresponding to the predetermined lipoprotein using electrophoretic pattern obtained by electrophoresis of a specimen; comparing the distance “a” and the distance “b” to determine a relative mobility “z(=b/a)” of the specimen to the standard sample, wherein the degree of modification of the predetermined component in the specimen being judged on the basis of the relative mobility “z”.

Abstract: A reaction apparatus for a biochemical examination is provided having at least a pair of band-shaped conveying members, a portion of each of which proceeds over a predetermined distance in the same direction in a closely contacted state, and which convey a sample-supporting thin film while sandwiching it between the closely contacted portions, and a heat source which is provided in the vicinity of the closely contacted portions of the pair of band-shaped conveying members, and which maintains at a predetermined temperature the sample-supporting thin film sandwiched between the closely contacted portions. The sample-supporting thin film is conveyed from one side to the other side between the pair of band-shaped conveying members. On the other side, the sample-supporting thin film is supplied with the reagent, then caused to approach the heat source while being sandwiched between the band-shaped conveying members.
