Figure 4. PB1 and PB2 exhibit greater protection than TCEP against METC disruption.
PB1 (100 μM) and PB2 (1 μM) significantly rescue RGC-5 cells to levels indistinguishable from control against menadione and antimycin A. TCEP does not result in significant protection against any of the METC-active compounds. ** (p<0.01).
