Figure 3. Effect of pH on accumulation of ASP+ (a fluorescent analog of MPP) and decynium 22 (D22) in cultured astrocytes.

Figure 3

a. Effects of application of buffer with different pH (pH=7.4; pH=8.4 and pH=6.4, subsequently) containing 1 μM of decynium22 on accumulation of D22 fluorescence in astrocytes (n=8).

b. Effects of application of buffer with different pH (pH=7.4; pH=8.4 and pH=6.4, subsequently) containing 2 μM of ASP+ on accumulation of ASP fluorescence in astrocytes (n=4). Note the striking similarity of pH dependence of accumulation of these dyes which suggests a similar pathway of transport.
