Figure 2From: Gene expression and activity of digestive proteases in Daphnia: effects of cyanobacterial protease inhibitorsSDS-PAGE and native gel of Daphnia homogenate. Activity stained SDS-PAGE of Daphnia homogenate (DH) or gut homogenate (GH) and a native PAGE of Daphnia homogenate. White bands indicate active proteases. Protein marker (M). Trypsins (T) and chymotrypsins (CT) are assigned according to Agrawal et al., 2005 [19].Back to article page
