Comparison of PAS polypeptides with conventional PEG precipitants. Chemical constitution of PA200 (a) versus PEG 3350 (b). (c) Side-by-side vapor-diffusion experiment using PA200 and PEG 3350 as precipitants for protein crystallization, with PEG 3350 serving as the common hygroscopic polymer solute in the buffer reservoir.
