FIGURE 4.

Scattering length density difference profile of NR measurements done on D₂O buffer subphase. In the CTB₅-monolayer case, the B₅ unit can be seen along with differences in the lipid region. In the CTAB₅-CTB₅ case, the A-unit can clearly be seen to be oriented away from the lipid layer. There is little-to-no change in the lipid region when CTB₅ and CTAB₅ are bound implying that there is little to no A-unit penetration before activation.
