Crystals of Pleurotus ostreatus (oyster mushroom) lectin have been grown by
the hanging-drop technique using ammonium sulfate as the precipitant at 29
3 K. Over a period of between two and three weeks, crystals of hexagonal bi
pyramidal morphology grew to maximum dimensions of 0.2 x 0.2 x 0.5 mm. The
crystals belong to space group P6(1)22 or P6(5)22, with unit-cell parameter
s a = b = 155.9, c = 149.8 Angstrom, V = 3 153 078 Angstrom(3), Z = 12 (ass
uming 50% solvent), and diffract to 4.1 Angstrom at 293 K.
