Figure 2

The AB, CD and AD peaks obtained after capillary gel electrophoresis. When only the Pkd1^lox allele is present two peaks, AB and CD, can be observed (Upper panel). A single peak, AD, is observed when only the Pkd1^del2-11 allele is present (Middle panel). When the Pkd1^lox and the Pkd1^del2-11 allele are both present, all three peaks can be observed (Lower panel).
