Figure 2. Immunohistochemistry of SCLC cell line NCI-H82 and colon carcinoma cell line HCT116. The results for MUM-4 and MUM-6 are shown, together with the staining with RNL-1, a monoclonal antibody directed to an extracellular part of NCAM. Cells were permeabilized with methanol/acetone as described^[5] or, for the MUM-6 panel, with 4% paraformaldehyde (15 min) and 0.5% Triton-X100 (10 min)
