Abstract: This invention provides hollow fibers impregnated with gel in which the gel firmly adheres to the inner walls of the hollow fibers due to the introduction of comb polymers on the inner walls of the hollow fibers. These hollow fibers impregnated with gel have no gaps at the interfaces between the inner walls thereof and the gel. Accordingly, analysis can be performed with high accuracy. Also, thin slices obtained by bundling these hollow fibers and then slicing this bundle have sufficient adhesion between the gel and the inner walls of the hollow fibers. This also prevents gel from becoming detached from the inner walls at the time of slicing or during operations such as hybridization.

Abstract: A microarray obtainable by slicing a block comprising a plurality of linear bodies or through-holes which carry an organism-related substance, in a direction intersecting the longitudinal direction of the linear bodies or through-holes, wherein the linear body and/or block comprise a substance that reduces the self-fluorescence thereof.

Abstract: An electrophoretic device in the form of a casing having inside sealed spaces isolated by an electrophoretic carrier. The device includes at least one liquid injection/discharge opening, communicable with the outside, on the outer wall of said sealed spaces. An electrophoretic method and a specimen detection method use the device. Additionally, an electrophoresis apparatus can have a structure for sandwiching the electrophoretic carrier between a pair of electrodes, and can have a space capable of holding liquid between the sandwiched electrophoretic carrier and the respective electrodes, and an electrophoretic method uses the same device.
