Dear Terry, 

You may want to look into using a dye called FM1-43. I know this can be
used to fill vesicles, and then various aspects of vesicle turnover can
be studied using microscopy. Look up papers by Tim Ryan to get an idea
how it's done.

It is the human moral will that saves us from violence, not the
presence or absence of weapons. We should reject utterly the absurd
that weapons are the cause of violence.  ALAN KEYES
