Problems solved by technology

As mentioned above, however, in the prior art it is difficult to know where in certain cells and / or which cells in a sample express the luminescent protein information, although the presence or absence of luminescent protein expression in the sample can be detected
Actually, with an ultra-high-sensitivity image detection element, low-light detection can be performed, but in this case, the image that can be obtained is only a mosaic image, and it is therefore difficult to perform detailed analysis while defining the area in which the amount of luminescence is to be measured

[0082] Image 6 A schematic diagram showing another embodiment of the low-light measurement device of the present invention, which can perform digital zoom or optical zoom, and as Figure 5 The same device simultaneously measures fluorescence and bioluminescence.

[0083] Referring to the drawings, in the embodiment, the measuring device itself, i.e. the optical microscope, is enclosed in a light-shielding box 54, wherein the bottom of the light-shielding box 54 is fixed on the chassis 55 by an obstacle 56, and thus the box is designed to prevent external light Enter the observation optical system 5. On the upper surface of the light-shielding box 54, a separate light-blocking cover 57 is installed, and one end of the light-blocking cover 57 is connected to the main body of the light-shielding box 54 through a hinge 58, so that the light-blocking cover 57 can be rotated and opened.

[0084] To acquire an illumination image, light for illumination, eg, from a light source 2 s...

Abstract

A novel apparatus and a novel method of imaging a luminescence phenomenon of a sample of biological origin using an optical image formation device are provided. In the inventive method and apparatus, an illumination image acquired by illuminating the sample and a luminescence image acquired with the light emitted by a luminescence phenomenon of a cell in the sample without illuminating it are superposed to generate a superposition image. In the superposition image, an analysis region is determined. Thereby, even when the light detected in a luminescence observation is feeble, a luminescent cell and / or a luminescent site in a cell in a sample can be specified.

Description

technical field [0001] The present invention relates to a method and device for imaging low light emitted by biological source samples (or specimens) such as cells, bacteria and other biological samples, more specifically, the present invention relates to low light imaging by bioluminescent phenomena And methods and devices for observing and various measurements of such samples. Background technique [0002] In recent years, techniques for imaging samples of biological origin, such as cells, with fluorescent proteins such as GFP, and / or luminescent proteins, such as luciferase, luminescent proteins, have been increasingly used in research in the field of life sciences. Expression in any cell by transgenesis. Fluorescent or luminescent proteins can be expressed while mixed with another arbitrary protein (protein marker) in the cell, and will only be based on specific genetic regulation if a fluorescent or luminescent protein-encoding gene is inserted or replaced downstream o...
