Peptides Enhance Resolution (IMAGE) University of Würzburg Caption Synapses of brain cells: Here, the pre-synapses are tagged conventionally with antibodies (red); the post-synapses are labelled with special peptides which clearly enhance resolution. Post-synapses and synapses are shown in a resolution of about 130 nanometres.
