Dewaxing and heat antigen retrieval steps. (A) Twelve histological staining boxes are cleaned, labeled accordingly, and filled with the related solutions. (B) The paraffin section slides are distributed in staining racks. (C) After dewaxing, the slides are transferred to glass staining racks and then to glass staining containers (D) filled with the unmasking solution. (E) The container with the slides is microwaved for 3 min after boiling, cooled down to approximately 50°C using an ice box (F) and then microwaved again for 3 min.
