Immunocytochemical detection of brain neurons using the selective marker NeuN.
The aim of the present work was to develop optimal protocols for immunocytochemical reactions for nuclear protein NeuN for light and laser confocal microscopy which avoid the thermal antigen demasking procedure, which degrades the state of the tissue and requires use of expensive adhesive-coated slices. Maximal antigen retention was obtained after fixation in zinc-formalin and Bouin's fluid (maximum one day). Two protocols are proposed allowing the thermal demasking procedure to be avoided during detection of neuron marker NeuN on paraffin sections examined by light and confocal microscopy.
