Figure 2. Comparison of extracts from non-irradiated control teeth with those from in vitro irradiated teeth demonstrates that the protein composition of MMP-20 is unchanged and that MMP-20 retains its activity.

Figure 2

A, Representative densitometric scans for MMP-20 bands after western blotting demonstrate no significant change in the banding pattern for MMP-20 in in vitro irradiated teeth as compared to their paired controls. B, Western blot for MMP-20 in extracts from control and in vitro irradiated teeth. C, Casein gel zymography on a series of extracts shows MMP-20 activity profile in the in vitro irradiated teeth is similar to that in the matched pair controls. KEY: Numbering of gel lanes refers to corresponding, individual tooth extracts.
