Figure 3. DPI of Pgn interactions with Str enolase.

The silicon oxynitride chip was injected once with 200 µL 4.4 µM Pgn and the injection stopped halfway. It was then injected with another 4.4 µM Pgn which indicated that the chip was saturated. This was followed by two injections of 5.3 µM Str enolase. The two lower curves indicate the calculated average masses of the proteins bound to the chip while the two upper curves indicate the average heights of the adsorbed layers.
