We report here a method that allows simultaneous visualisation of two antigens within single neurones. In essence this involves the combined use of horseradish peroxidase and alkaline phosphatasereactions to visualise two markers. Using this method we show that ChAT-and CGRP-like immunoreactivity can be co-localised within single neurones of the V to VII motor nuclei. In the case of the V motor nucleus, we show that each marker can be localised in motoneurones labelled with horseradish peroxidase.
