Notes:
The class I major histocompatibility (MHC) antigen HLA-B27 was purified by immunoaffinity chromatography from the homozygous human B lymphoblastoid cell line LG-2. Detergent-soluble HLA-B27 was cleaved with the protease papain to remove the hydrophobic transmembrane region and the cytoplasmic tail. Crystals of the resulting water-soluble extracellular fragments were obtained in hanging drops by the vapor-diffusion method. The crystals are triclinic, space group P1, with unit cell dimensions a = 45.9 Å, b = 71.0 Å, c = 83.7 Å, α = 79.4°, β = 88.5°, γ = 89.9°, and diffract beyond 2.5 Å resolution.
