Fig. 1From: Express photolithographic DNA microarray synthesis with optimized chemistry and high-efficiency photolabile groupsThe optimal coupling times for Activator 42, DCI, ETT and BTT were determined in microarray synthesis and hybridization experiments. DCI and ETT activators result in maximum hybridization signal at very short coupling times whereas the hybridization signal from arrays synthesized with BTT and 42 increases with coupling time.
