Crystals of bacterially expressed plasminogen activator inhibitor (PAI‐1) suitable for X‐ray diffraction analysis have been obtained from 8% (w/v) PEG 1500, pH 8.25. The space group is P 1, and the lattice constants are a = 82.17 Å, b = 47.82 Å, c = 62.89 Å, α = 90.00°, β = 106.90°, γ = 106.84°. The diffraction limit is 2.3 Å, and the unit cell contains two molecules of PAI‐1. The crystals contain latent PAI‐1 which can be partly reactivated by exposure to denaturants.
