Figure 4. The ability of Indo to influence detergent resistant membrane against detergent effects of triton X-100.

Figure 4

A) Higher turbidity measurements were obtained in DOPC/DPPC/Chol (1∶1∶1) membrane exposed to 2.5 mM Indo, indicating a better ability of the mixed membrane exposed to Indo to resist the detergent effect of triton X-100 (p<0.05). B) The ability of pure DPPC to resist triton X-100 solubilization was also increased significantly (p<0.05) by 2.5 mM Indo. C) The ability of pure DOPC to resist the detergent effect of triton X-100 was significantly diminished by 2.5 mM Indo (p<0.05). D) The contrasting effect of changing Indo concentrations on detergent resistance of DPPC (closed diamonds) and DOPC (open squares) against triton X-100. Different levels of triton X-100 were used for each lipid type to achieve optimal solubilization: 30 µl for DPPC or 9 µl for DOPC (See Method section).
