3 microliters of purified aldolase was applied to grids and manually blotted for four to five seconds using Whatman No. 1 filter paper. Blot time counting commenced once the blotted sample on the filter paper stopped spreading, monitored visually using a lamp positioned behind the sample. At the end of 4-5 s, the blotting paper was pulled back and immediately plunged into a well of liquid ethane cooled by liquid nitrogen..
Lyophillized rabbit muscle aldolase was purchased (Sigma Aldrich) and solubilized in 20 mM HEPES (pH 7.5), 50 mM NaCl at ~3 mg/ml. Aldolase was loaded onto a using a Sepharose 6 10/300 (GE Healthcare) column equilibrated in the solubilization buffer, and fractions corresponding to apoferritin were pooled and concentrated to 1.6 mg/ml.
