Morphology of breast tumors exposed to methacarn or RCL2 fixatives. A breast carcinoma sample was either fixed in FAAM (A, E), NBF (B, F), methacarn (C, G), or RCL2 (D, H) before paraffin-embedding. A representative view of H&E-stained sections is presented. Similar views were obtained for five additional invasive breast carcinomas. Original magnifications: ×100 (A–D); ×400 (E–H).
