  • These antibodies are frequently employed for immunolocalizing alpha7 nicotinic acetylcholine receptors.

    • Conclusions:

    • The findings raise critical questions about the validity of current immunolocalization data for alpha7 nicotinic acetylcholine receptors.
    • Histologists must critically assess the 'real' labeling observed in their experiments.
