Characteristic cDNA-AFLP patterns are generated by individual restriction enzymes. Overview of the Homo sapiens selective cDNA-AFLP PCR arrays for all enzyme combinations tested here. The layout of arrays follows Figure 2. Note the consistent patterning of arrays, with characteristic ridges and trenches for enzyme combinations which contain the same enzyme. Arrays above the diagonal are mirror images of those below the diagonal. Selective primer combinations yielding no amplifications are highlighted in white. The pixel intensity indicates the relative proportion of fragments amplified in a given selective PCR combination.
