High yields of staphylococcal enterotoxin C2, from Staphylococcus aureus, have been purified using dye ligand chromatography. Crystals suitable for X-ray diffraction work were obtained by vapour diffusion using ammonium sulphate and polyethylene glycol as precipitants. They belong to the tetragonal space group P4122 with unit cell dimensions a=b=43.2 Å and c=290.9 Å with one molecule per asymmetric unit. The crystals diffract to at least 2.8 Å resolution and arc suitable for three-dimensional X-ray structural analysis.
