Crystallization and preliminary X-ray studies of human vascular anticoagulant protein

The human vascular anticoagulant protein, a 36 kDa member of the annexin/lipocortin family, has been crystallized using polyethylene glycol 20,000, by the vapour diffusion method. The crystals are monoclinic, space group P21, cell dimensions a = 83·9 A, b = 80·9 A, c = 71·4 A, β= 108·7 ° and diffract to at least 2·2 A resolution.
