(A) Grayscale fluorescence scanner image of SA-EITC bound to biotin-BSA printed microarrays. Scan at 50 db gain with 532 nm excitation and 551 nm PMT detection with a 25 nm bandpass filter. (B) Grayscale fluorescence scanner image of SA-FITC bound to biotin-BSA printed microarrays. Scan at 50 db gain with 532 nm excitation and 551 nm PMT detection with a 25 nm bandpass filter. (C) Bright field optical microscopy example image of a microarray sample tagged with SA-FITC after photopolymerization at 30 mW/cm² for 10 minutes.
