Electron microscopy in the biological sciences can be divided into
two disciplines. The first, concerned with high resolution detail
of particles or periodic structures, is mostly based on sound
theoretical principles of physics. The second, by far the larger
discipline, is interested in the information obtainable from thin
sections. The theoretical back ground to those groups of techniques
for preparing and looking at thin sections is often inexact and
"loose," for want of a better word. What should be chemistry is
often closer to alchemy. This kind of electron microscopy is often
enshrined with mystical recipes, handed down from generation to
generation. Admittedly, many of the processes involved, such as
those required to embed tissue in epoxy resins, involve multiple
interconnected steps, which make it difficult to follow the details
of anyone of these steps. If all these steps are shrouded in some
mystery, however, can one really trust the final image that emerges
on the EM screen? When we present the data in some semi
quantitative form is there really no better way to do it than to
categorize the parameters with ++, +/-, etc? What happens when one
labels the sections with antibodies? Does the whole business necess
arily need to be more of an "art" than a "science"? Upon reflecting
on these problems in 1981, I had the impression that many of the
multi-authored textbooks that existed then (and that have appeared
since) tended to exacerbate or at least perpetuate this"
