Figure 8
Diagram illustrating the counter-diffusion method for growing protein crystals. Here, the protein solution is shown in red and the gel saturated with the precipitant solution is shown in green. The capillaries are sealed at their distal end but are open where they enter the gel. By diffusion of precipitant up the length of the capillary, a concentration gradient is formed that explores a wide range of precipitant conditions.
