Structure of Bence—Jones protein, Pav: an initial report

A Bence-Jones protein, Pav, was isolated from the urine of a myeloma patient. Crystals were grown by five different methods yielding different morphologies with slightly changed cell parameters, but the space group was the same (P212121) in every case and X-ray patterns appeared to be identical. The cell parameters are: a = 93.6 (4) to 95.1(4) Å, b = 92.7(3) Å and c = 72.8(2) Å. The crystal density and solvent content are approximately 1.128...
