Comparison of typical CD spectra of LHCII in the presence and absence of detergent. A, LHCII trimers trapped in polyacrylamide gel: the gel was dialyzed for 2 h to remove the detergent β-DM first (dashed line), then 0.1% β-DM was added to the dialyzed gel (solid line). B, LHCII trimers in dialyzed gel (solid line) and aggregates in detergent-free buffer solution (dashed line). All CD spectra are normalized to the absorbance at 675 nm. C, CD difference spectra of LHCII in gel with β-DM minus dialyzed gel (solid line) and aggregates minus dialyzed gel (dashed line).
