WOW, Julie, that is an AMAZING picture!!!! You ought to post that! The microscopic world is full of wondrous images once they are magnified so we can see! Thanks for posting that. I am glad to be able to see the differences in cellular shape betweent the cone and rod photoreceptor cells! Great stuff on how you prepare your samples too!
We have used both of these electron microscopic techniques for our work. And people even use variations of this technique to determine proteins' structure, i.e. the magnification level is even greater such that you can resolve distance/3-D shape in order of angstrom.
