Figure 10From: Efficiency, error and yield in light-directed maskless synthesis of DNA microarraysDose calibration curve using direct fluorescent end-labeling with Cy3. A single base (dT) was coupled uniformly over the glass substrate and different areas (images at the bottom) were exposed to different doses of light before the final coupling with a Cy3 phosphoramidite. The time constant for photodeprotection Ï„ equals approximately 2.5 J/cm2.Back to article page
