Figure 6.

Average measured droplet fluorescence intensities from three repeats of 650 unique MMP–substrate combinations. The labels indicate the corresponding reagent (e.g., SB3, MMP1, etc.). For each reagent, five different concentrations were tested. For each MMP, the concentration increases from top to bottom, whereas for each substrate, the concentration increases from left to right. The top row in each repeat indicates results from a substrate-only control in which no MMPs were used.
