Investigations on the Use of Graphite Electrodes Using a Hull-Type Growth Cell for Electrochemically Assisted Protein Crystallization

This paper describes the use of an electrochemical Hull-type cell adapted for protein crystallization evaluating three inclination angles (45°, 60°, and 90°). For optimization experiments, classical platinum wire electrodes were used, and once the best geometry was known, they were replaced with 0.5 mm diameter low-cost graphite automatic pencil leads. Using Pt and graphite, the cell with electrodes fitted at 90° showed the most favorable...
