Digestion of human serum in the presence of EFNase. EFNase (final concentrations as indicated) was incubated with human serum (25 μl) at different time intervals during the degradation and then aliquots were taken for SDS-PAGE (panel A). Under the same conditions, serum in the absence of EFNase was used as negative control (panel B). Panel C was the comparison of the hydrolytic activity of EFNase and trypsin by densitomitric scanning analysis of Figure 2A and Additional file 1B.
