Effects of lowered pH on scaffold-containing capsids. Purified B capsids were dialyzed against PBS at pH 7.2 (a and c) or pH 5.5 (b and d) for 16 h at 4°C in the presence of 1 mM DTT. The capsids were then either used for negative staining (a and b) or prepared for thin sectioning (c and d) and examined by electron microscopy. Bar, 200 nm.
