Fig. (2) Effects of ALA and stearic acid on membrane fluidity as measured by DPH florescence polarization. DPH loaded thymocytes were incubated with ALA or stearic acid (20 and 30µM) for 1 and 2 hrs. While ALA increased membrane fluidity, the saturated stearic acid caused a decrease in membrane fluidity. Increased florescence reflects a decrease in membrane fluidity. * Significantly different from control (p< 0.05).
