Effects of electropermeabilization and gene electrotransfert on the   lateral mobility of a GPi anchored protein
  Electropermeabilization is a method by which molecules can be introduced in living cells through the plasma membrane. Here, we show that electropermeabilization affects the lateral mobility of Rae-1, a GPi anchored protein. Our results shows that 10 to 20 % of the membrane surface is occupied by defaults or pores. Gene electrotransfert also affects the lateral mobility of Rae-1. Furthermore, we clearly show that once inserted into the plasma membrane, DNA totaly excludes Rae-1, indicating that DNA molecules are tightly packed together to forms huge aggregates.
