FIELD: chemistry.
SUBSTANCE: described are: solution for preliminary processing for immunohistochemical staining, which elutes paraffin-containing mounting medium from microscope slide with tissue sample, embedded into medium, and extracts antigenicity of tissue sample, and which can be used three or more times, and solution concentrate for preliminary processing for immunohistochemical staining, which provides possibility of easy obtaining of solution for preliminary processing. Solution for preliminary processing for immunohistochemical staining contains antigen-extracting agent, certain non-ionic surface-active substances in specified range and cyclodextrin or its derivative in certain amount, with not less than 80% of water constituting the remaining part. Composition of antigen-extracting agent is such that pH of solution for preliminary processing is in specified range, and content of cyclodextrin or its derivative represents specified amount.
EFFECT: obtaining solutions for preliminary processing for immunohistochemical staining.
