CD analysis of monomeric httNTQN peptides in Tris–TFA, pH 7.4. (a) Concentration dependence of the CD spectra of httNTQ: green, 1.3 mM; blue, 0.67 mM; orange, 0.33 mM; black, 0.15 mM; red, 0.10 mM obtained by dilution from a 0.76-mM solution. All samples were analyzed in a 0.1-mm-path-length cell, except for the 0.10- mM sample, which was analyzed in a 0.1- cm cell. (b) Secondary-structure contents calculated (Materials and Methods) from CD curves, obtained in a 0.1- cm-path-length cell, of the following samples: httNTQ3, 36 μM (brown); httNTQ10K2, 32 μM (green); httNTQ15K2, 28 μM (yellow); httNTQ25K2, 25 μM (red); httNTQ35K2, 27 μM (black); httNTQ37-P10K2 20 μM (orange).
