The purpose of this chapter is to serve as a guide for those who wish to carry out experiments tracking single proteins in planar supported biomimetic membranes. This chapter describes, in detail, the construction of a simple single molecule microscope, which includes: (1) a parts list, (2) temperature control, (3) an alignment procedure, (4) a calibration procedure, and (5) a procedure for measuring the mechanical stability of the instrument. It also gives procedures for making planar supported bilayers on hydrophilically treated borosilicate and quartz. These include (1) POPC bilayers, (2) POPC/PEG-PE cushioned bilayers, (3) POPC/PEG-PE cushioned bilayers on BSA passivated substrates, and (4) a cushioned biomimetic membrane of the endoplasmic reticulum (ER).
