Diluted protein (in buffer containing zinc chloride and sodium chloride) was incubated on ice for 30 minutes after which it was applied to the grid, incubated for 30 seconds, and blotted for 3 seconds before plunging.

The protein was stored at 3.0mg/ml in 50mM HEPES (pH 7.5) and diluted immediately prior to grid preparation
