Figure 8.

Cytochalasin B does not inhibit overall axonal transport or perturb the steady-state distribution of axonal NFs. The panels present autoradiographs or immunoblots, probed with R39, of homogenates of retinas (R) and the first 5 × 1.1 mm segments of optic axons as described in the legend to Figure 7. The accompanying graphs present densitometric analyses of total radiolabeled proteins in autoradiographs or total NF-immunoreactive species in immunoblots. Note that cytochalasin treatment did not perturb overall axonal transport, nor did it reduce overall NF distribution under these conditions.
