Fig 2. CD wavelength spectra of unfolded monomeric, oligomeric, and folded OmpA₁₇₁.

Monomeric OmpA₁₇₁ (dotted red) was prepared at a concentration of 1 μM in 600 mM urea, 20 mM Tris, pH 8. Oligomeric OmpA₁₇₁ (solid red) was prepared at a concentration of 10 μM in 600 mM urea, 20 mM Tris, pH 8 and incubated for 16 h. Natively folded OmpA₁₇₁ (solid black) was formed by incubation with 800 μM diC₁₀PC LUVs at 1 μM protein in 1 M urea, 20 mM Tris, pH 8.
