From: Facile isolation and analysis of sporopollenin exine from bee pollen
Fluorescence imaging of mixed samples of sporopollenin grains with and without fluorescent coating. Sunflower (a,b) and Rape (c,d) sporopollenin exine shells with and without RBITC coating. By using mCherry filtercube (a,c), only the coated grains can be shown, while the non-coated ones are glowing only weakly. Brightfield image (b–d) shows all of the grains.
