title: Crystallization of and preliminary X-ray data for the plasma retinol-binding protein.
abstract: Crystals of the human and rabbit plasma retinol-binding proteins have been grown from solutions of polyethylene glycol 6000 and CdCl2. Two crystal forms have been observed for the human protein, while the rabbit protein has only crystallized in one form which is isomorphous with one of the human serum retinol-binding protein crystals. The crystals differ in their morphologies, but are both in space group P212121 and have similar unit cell sizes (a = 45.9, b = 53.3, c = 72.0 A and a = 45.7, b = 48.7, and c = 76.5 A). The crystals diffract to approximately 2.0 A resolution. In both cases there is 1 molecule/asymmetric unit.
