Confocal images of immunolabelled cassava sections treated with buffer (control) and with the NSPase product (dosed at 250 and 400 ppm) were taken using a IX83 Confocal Laser Scanning Microscope (Olympus, Japan). All samples were analysed with a 20x objective. Alexa-555 fluorescein-signal was excited at 561 nm (green) and detected in an emission spectrum between 570–620 nm, designated as red in the software. Cassava samples were excited at 405 nm (blue) and autofluorescence emission was observed within 429–470 nm, designated as green in the software.
The images were processed using the FV31S-SW software (Olympus, Japan).
