FIG. 9.

Effect of CAV-1 or CPV capsids on the permeability of cells to the protein synthesis inhibitor α-sarcin. CPV full capsids or CAV-1 particles at the concentrations shown (particles per milliliter) were incubated with A72 or tTA-Mv1Lu cells with or without 100 μg of α-sarcin per ml for 90 min at 37°C and then incubated with [³⁵S]methionine for an additional 1 h. Incorporated [³⁵S]methionine was measured by scintillation counting. Results are expressed as the mean and standard deviation of three separate dishes.
