    摘要: A method of purifying a target protein from a solution, in which the target protein containing an electron transfer protein is dissolved, with the use of liquid chromatography. The liquid chromatography is performed by introducing the above-described protein solution into a tank filled with a packing agent, thus bonding the target protein to the packing agent, removing impurities, and then eluting the target protein from the packing agent with the use of an eluent containing a hydroxycholanoic acid salt. As an example of the above protein, glucose dehydrogenase containing a protein having an activity of dehydrogenating glucose is cited. The liquid chromatography is performed by combining hydrophobic chromatography with anion exchange chromatography.

    摘要: A sensor storage container is provided that allows sensors to be checked visually from the outside. A container is used for storing sensors including an oxidation-reduction enzyme that oxidizes or reduces an object to be analyzed, a mediator that mediates the transfer of electrons caused by oxidation or reduction, and a detection means that detects the oxidation or reduction reaction. The container is transparent or semi-transparent in whole or in part and thereby the sensors can be checked visually from the outside of the container. This container may be composed of a container body and a lid. The container body may be provided with a scale. Preferably, the sensors are those produced using a ruthenium metal complex as the mediator.
