Abstract

The present disclosure relates to a gel-phase patch that performs a function of assisting in staining during a staining process such as a process of coming into contact with a specimen such as blood to perform a staining function of staining the specimen, a process of fixing the specimen, or a process of forming an optimal pH at a specimen stained by a staining sample. According to an aspect of the present disclosure, a contact-type staining patch includes a staining solution that reacts with a specimen and a gel receptor provided as a gel matrix of a mesh structure in which a pore that accommodates the staining solution is formed and the mesh structure prevents the staining solution in the pore from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer some of the staining solution to the specimen.

Claims (7)

1. A method of staining a specimen using a gel-phase contact-type staining patch that contains a staining solution configured to react with the specimen, the method comprising:

staining a specimen placed on a slide with a staining solution,

wherein, the staining step comprises,

contacting a surface of the gel-phase contact-type staining patch to the specimen; and

separating the gel-phase contact-type stating patch from the slide.

2. The method of claim 1 , wherein, in the staining, the gel-phase contact-type staining patch maintains the staining solution in a state in which a reaction condition of the specimen is satisfied.

3. The method of claim 1 , further comprising, after the separating, omitting processes of washing and drying the specimen and observing the stained specimen.
