FIGURE 2 in MIDTAL (Microarrays for the Detection of Toxic Algae)

FIGURE 2: Spotting scheme for the first generation MIDTAL microarray. In the upper panel the supergrid arrangement on each slide is shown. Each supergrid is composed of four grids. In the lower panel each grid is shown in more detail. Only two of the grids in each supergrid are hybridised in each experiment. Each probe is spotted four times, hence the four colors adjacent to one another. Each box in the cluster of four colors in the grid represents a spot of c. 50 µm in diameter where a given probe is immobilized. This generation of the microarray has 960 spots, covering 112 probes for toxic algal species and higher taxon levels, and various positive and negative control probes.
