Samples were diluted to 0.1 mg/mL in 20 mM HEPES buffer, pH 7.4, with 5% glycerol, 150 mM NaCl, and 7.5 mM glutaraldehyde. After 5 minute incubation at room temperature, sufficient 1 M Tris stock, pH 7.4, was added to a final concentration of 75 mM Tris to quench unreacted glutaraldehyde, and was then incubated 5 minutes. Sample was then applied to a carbon film over 400 mesh copper EM grids that had been glow-discharged, incubated 1 minute, and then stained with 2% uranyl formate.
