The present invention relates to biological substance-immobilized fibers wherein a biological substance is immobilized on a fiber, fibers retaining a biological substance-immobilized gel, and fiber alignments having bundles of the above-described fibers and slices of the same.

Carriers having biological substance

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.

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.

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.

An object of this invention is to provide a lens array in which the amount of light reaching the image forming surface is large and the variation in the amount of light is small. In order to achieve this object, the lens array comprises cylindrical graded index lenses of radius r wherein the refractive index continuously decreases from the center of the lens toward the periphery, said cylindrical graded index lenses are arranged in one line or plural lines with array pitch 2R, if R is R&gE;r &gE;0.8R and if the refractive index profile of each graded index lens is approximated by n(r) &equals;n &lcub;1&minus;(g&middot;r) &rcub;, the overlapping degree m defined by m&equals;X /2R satisfies 1.05&lE;m&lE;1.2, wherein, said r is the distance from the optical axis, n(r) is refractive index at the distance r from the optical axis, n is the refractive index at the center, g is the refractive index profile constant, X is the radius of the field of view (X &equals;r cos(Z &pgr;/P), r is the effective radius of the graded index lens, Z is the length of the graded index lenses, and P is the period length of the graded index lenses namely P&equals;2&pgr;/g.

A color image scanner is constructed by a three primary color LED array ( ) for illuminating an original ( ) to be read out, a monochromatic image sensor array ( ) and a rod lens array ( ) disposed between the original ( ) and the image sensor array ( ). The focusing parameters of the three kinds of refractive index distribution type rod lenses ( ) constituting the rod lens array ( ) are set so that each of the operating wavelength band and the predetermined wavelength is different among the kinds, the lens length Z is equal among the kinds, and the conjugate length TC at each predetermined wavelength is substantially equal among all the kinds. Accordingly, when a color image reading operation is carried out by using the rod lens array which is effective in compactness and brightness, the chromatic aberration of the rod lens array can be sufficiently reduced and high-resolution can be implemented at low cost.
