Protein crystallization using PA200 as a precipitant. (a) HEL and (d) FaOMT crystallized in the presence of 6.25%(w/v) PA200. For HEL (b) and FaOMT (e), spherulite formation was observed in the presence of 3.125 or 6.25%(w/v) PA200 approximately two weeks after the single crystals had appeared. HEL (c) and FaOMT (f) crystallized in the presence of 6.25%(w/v) PEG 3350 are shown for comparison (see Fig. 2). |
