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.

Hollow fiber having inner wall into which comb polymer is introduced, hollow fiber impregnated with gel, and thin slice of fiber array

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.

Method for producing a microarray

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.

Device for electrophoresis, electrophoresis equipment, electrophoretic method, and specimen detection method

By the present invention, there is provided a fiber having nucleic acid immobilized thereon, an alignment of fibers having nucleic acid immobilized thereon, and a slice thereof.

Carriers having biological substance

Disclosed is a graded index type optical fiber having a multilayer structure comprising a plurality of concentrically arranged non-blended layers LNB to LNBm formed of (co)polymers P to Pm selected from the group consisting of two or more homopolymers HP HP . . . and HPn composed of units of vinyl monomers M M . . . and Mn, respectively (provided that the refractive indices of the homopolymers decrease in that order), and one or more binary copolymers CPs composed of units of vinyl monomers M M . . . and Mn, each of (co)polymers P to Pm having a glass transition temperature (Tg) of 80&deg; C. or above, wherein the refractive index is highest at the center of the multilayer structure and decreases gradually toward the outer periphery thereof. This optical fiber has a small transmission loss, a large numerical aperture, and excellent resistance to moist heat.
