Seminiferous vessels stained for cytokeratin 18 without (upper) and with (lower) antigen retrieval Chemically fixing tissue sections may lock in a good result for the world to see, but it can complicate subsequent immunohistochemical staining by masking relevant antigens. A process known as antigen retrieval can restore the antigenicity of proteins altered by fixation and improve immunohistochemical detection. It can also reduce background staining, which makes it an important step in developing
