Partial Review list for Biology 555

Several copies of the textbook Scanning and Tramsmission Electron Microscopy by Flegler et al are available in the Reserve Room in Love Library

You might find it useful to review the chapter on Enzyme cytochemistry (pp 283-289) and Immunocytochemistry (pp 263-278) in Electron Microscopy by Bozzola and Russel, also in Reserve Room

We discussed a number of pieces of equipment necessary to prepare or view samples for an electron microscope.  Here is a list of most of the equipment I diagramed and/or presented in lecture.  You are still  responsible for any devices discussed in the text, but not necessarily presented in lecture.

Diagram the parts, and explain the operation of:

Scanning probe microscope (i.e., Atomic force or scannning tunneling) (general overview of how one works)

TEM (column and imagers)

SEM (column and detectors)

Gun assembly(including anode plate)

Electromagnetic lens and polepiece

Rotary mechanical pump

Oil diffusion pump

Turbomolecular pump

Titanium sublimation pump

Diffusion-pumped vacuum system

Turbo pumped vacuum system

Slam freezer, propane jet freezer, plunge freezer

Vacuum evaporator(shadowing, replica making)

Ultramicrotome

Sputter coater

Critical Point dryer

EDS detector

WDS detector

Photographic paper or film

Laser printer

Digital interfaces for TEM


Discuss the protocol steps for sample preparation (see also Bozzolo et alon Reserve List)

SEM morphological examination

SEM microanalysis (EDS or WDS)

TEM cryosectioning

TEM morphological examination

TEM pre-embedding immunolabelling

TEM post-embedding immunolabelling

TEM cytochemical labelling

TEM freeze substitution

TEM shadowcasting

TEM negative staining
