Protein crystals of bacteriorhodopsin grown in a PE-based bilayer gel, imaged under both visible and UV light. (a) Brightfield on an Olympus SZX-12 stereomicroscope. (b) White LED illumination with Ultrafluar 32× on a modified Zeiss UEM microscope. (c) 280 nm UV illumination with Ultrafluar 32× in the same frame as (b). (d) 280 nm UV illumination with Ultrafluar 32× of the smallest crystals in the field, which are 2–5 µm across. Scale bars represent 50 µm.
