Now I would like to show you that individual polypeptides can be accurately and rather easily viewed with the TEM without significant beam damage. The example is a cyclic dodecapeptide, Bactracin. This cyclic peptide is a familiar antibiotic. Let's take a look at a gallery of various molecules in different orientations in the next slide, but first, here is the space-filling model so that you can see what we will be imaging.
