Abstract: An apparatus for clearing tissue using electrophoresis according to an embodiment of the present invention comprises: a chamber which can contain therein a buffer solution and the biological tissue and has an inlet port and an outlet port for circulating the buffer solution; a support member, located within the chamber, for supporting the biological tissue; and electrodes located within the chamber and formed separately of a first electrode and a second electrode which correspond to each other. With the apparatus, it is possible to minimize the degradation of decomposition efficiency and quickly clear the tissue compared to a conventional apparatus.

Abstract: An excitation light from a first light source is adapted to be irradiated to a subject without passing through an objective lens so that the first light source and the subject may be arranged to be adjacent to each other. As a result, an excitation light having a high intensity of radiation may be irradiated to the subject to obtain a strong fluorescence signal. In addition, since the optical path of the excitation light from the first light source and the optical path of the fluorescent emission light emitted from the first dichroic mirror and the white light do not coincide with each other, a high S/N ratio may be obtained.

Abstract: Disclosed is a microchip. The microchip of the present invention is characterized by comprising: a first plate; and a second plate coupled to the first plate to form a channel, wherein the first plate comprises: a channel cover part; a first connection part spaced apart from the outer periphery of the channel cover part by a certain distance; and a tensile strength generation connecting part for mutually connecting the channel cover part and the first connection part so that the channel cover part elastically contacts the channel region formed on the second plate when the first plate is coupled to the second plate. According to the present invention, the channel cover part forming the channel elastically contacts the channel region formed on the second plate, thereby providing a microchip capable of providing a channel having a stable structure.

Abstract: A method of deciding detachment time of cells, and a method and apparatus for subculturing the cells using the method. The method of deciding detachment time of the cells from a culturing vessel using a separation enzyme in subculturing the cells includes: a photographing step of photographing an image of the cells treated with the enzyme; a computing step of calculating a contrast value of the photographed image, and computing a change rate of the contrast value; a comparison step of repeating the photographing step and the computing step until an increasing change rate of the contrast value is reduced to a predetermined change rate or less; and a reporting step of reporting a time to remove the enzyme from the cells and to detach the cells from the culturing vessel when the increasing change rate of the contrast value is reduced to the predetermined change rate or less.

Abstract: Disclosed is a microscope module. The microscope module includes an objective lens magnifying an image of a sample subject for observation; an observation part for observing the image of the sample magnified through the objective lens; and a reflective mirror provided between the objective lens and the sample such that the vertical distance between the sample and the objective lens is substantially reduced. Since the reflective lens is disposed between the objective lens and the observation part, the working distance from the sample to the objective lens is substantially reduced, so that the height of the microscope is remarkably reduced. Thus, the microscope may be used in a place with vertical spatial limitations.
