IHC was performed as published previously (Nettersheim et
al
, 2015
). Tumour tissues were dissected, fixed in 4%
formalin overnight and processed in paraffin wax. Signal detection was performed
semi-automatically in the Autostainer 480S (Medac, Hamburg, Germany). Nuclei were
stained by hematoxylin. IF was performed as described previously (Nettersheim et al, 2011c (link), 2015 (link)). Nuclei were stained by Hoechst 33342. See Table 1 for antibody details and dilution ratios.
