Figure 1.
A typical microarray image. This slide contains 6000 spots, arrayed in a set of 4 × 4 subarrays each containing 21 × 18 spots. The spots are printed with ∼130 μm center-to-center distances. The image was acquired using a CCD-based system using a DAPI counterstain to directly identify the spots. Spot shapes include circular, elliptical, and nonconvex perimeters.
