Fluorescence microscopic images of S-layer coated polyelectrolyte capsules. Images of filamentous polyelectrolyte capsules with HiLyte Fluor™ 488 amine linked S-layer polymer proteins in phase contrast mode (A), and excited by light in the 480–570 nm wavelength range using the filter U-MSWG (B). Polyelectrolyte capsules without S-layer proteins treated with HiLyte Fluor™ 488 amine in phase contrast mode are shown in image (C) and excited by light in the 480–570 nm wavelength range using the filter U-MSWG are shown in image (D).
