Figure 8.
Ai of F-actin and EGFR from serial optical sections through a single cell, showing close correlation of the subcellular localization of F-actin (A) and EGFR (B). An Ai value >0 indicates higher fluorescence intensity on the cathodal facing side; therefore, values close to 1 indicate extreme cathodal asymmetry of F-actin or EGFR. Each section is 0.5 μm thick.
