- Olympus Stream Basic was used.
- the color channels of the images can be separated into RGB colors.
- the evaluated area of the images must be chosen appropriately so that only the slide is displayed in the histogram.
- the fluorescence value is determined based on the blue value at 365 nm excitation wavelength.
