Phospholipid Head Groups Provide Differentially Stable Membrane Environments for Vitamin E

Abstract

values of donor and acceptor probes. Since FRET depends on the distance between donors and acceptors, and this distance depends upon the domain size, this study makes possible the measurement of nanodomain size. We found domain sizes of 10.0 5 2.5 nm of radius for nanodomains in DSPC/POPC/ Chol and bSM/POPC/Chol.
