Abstract

Proposed is an image calibration slide including: a substrate; and an image calibration pattern formed on a surface of the substrate, in which the image calibration pattern is formed by immobilizing and staining a DNA strand.

Claims (14)

1 . An image calibration slide, comprising:

a substrate; and

an image calibration pattern formed on a surface of the substrate,

wherein the image calibration pattern is formed by immobilizing and staining a DNA strand,

wherein the image calibration slide comprises at least two image calibration patterns that differ in color density from each other, and

wherein DNA strands immobilized in the at least two image calibration patterns have different densities.

2 . The image calibration slide of claim 1 , wherein the image calibration pattern is formed by immobilizing the DNA strand on the surface of the substrate that has been subjected to a surface treatment to immobilize the DNA strand, and then staining the DNA strand.

3 . The image calibration slide of claim 2 , wherein the surface treatment is performed on an entire surface of the substrate, and the DNA strand is immobilized on the surface of the substrate according to the image calibration pattern.

4 . The image calibration slide of claim 2 , wherein the surface treatment is performed according to the image calibration pattern, and the DNA strand is immobilized on the surface of the substrate that has been surface treated according to the image calibration pattern.

5 . The image calibration slide of claim 2 , wherein the surface treatment is performed to immobilize the DNA strand by covalent bond.

6 . The image calibration slide of claim 1 , comprising: the at least two image calibration patterns that differ in shape or size from each other.

7 . The image calibration slide of claim 2 , comprising: the at least two image calibration patterns that differ in shape or size from each other.

8 . The image calibration slide of claim 1 , comprising: the at least two image calibration patterns that differ in color from each other.

9 . The image calibration slide of claim 1 , wherein the at least two image calibration patterns have different dyes from each other.
