Turbidity increase of liposomes in the presence of tRNA

Liposomea	ΔOD405 (a.u.)b
POPC	0.003 ± 0.015
POPC/Ch(90/10)	−0.001 ± 0.001
POPC/Ch(70/30)	0.074 ± 0.026
POPC/Ch(50/50)	0.029 ± 0.045
POPC/DOTAP(70/30)	0.357 ± 0.003
POPC/DOTAP(50/50)	0.142 ± 0.002
DOTAP	0.162 ± 0.003

The final concentration of tRNA was 2.2 µM.^a The lipid concentration was 1 mM for POPC/Ch and 1.17 mM for POPC/DOTAP.
