Recording of signals from peptide arrays. After incubation with activated fluorochromes, the peptide array slides were washed in the incubation buffer without fluorochrome followed by washings in n-methylpyrrolidone and dichloromethane and airdried. Images of the arrays were recorded using a MVX10 microscope equipped with a MT10_D fluorescence illumination system and a XM10 CCD camera (all from Olympus). The excitation wavelength was 530-550 nm and the emission filter was 575-625 nm. The images were analyzed using the PepArray analysis program (Schafer-N, Copenhagen Denmark).
