Fig. 6.

Melting behavior of heat treated monomeric and oligomeric Bax. The thermal stability of monomeric (black) and oligomeric (red) Bax is shown. The upper panel depicts the decrease of the alpha helical content of Bax during the temperature increase, estimated from CD spectra taken at different temperatures. The alpha helical content of Bax heated to 90 °C and recooled to 4 °C is highlighted by arrows. The lower inset panel indicates the decrease of the ellipticity at 222 nm measured during the whole temperature increase
