Color-coded cells
This shows different colors of Qdot nanocrystals fluorescing within single cells. Here microtubules are stained with green-emitting QdotTM 525-streptavidin and mitochondria are stained with red-emitting QdotTM 605-streptavidin in NIH 3T3 mouse fibroblasts. The nuclei have been counterstained with
Hoechst blue dye. (Credit: Quantum Dot Corporation)
