Two stacked rings made from pairs of oppositely “supercharged” green fluorescent proteins (GFPs). Colors correspond to the actual fluorescence wavelength of the GFP molecules; the ribbons are derived from the structural model validated by observing cryogenically frozen proteins with an electron microscope.
