Preliminary crystal structure analysis of an Fab specific for a Salmonella O-polysaccharide antigen

J Mol Biol. 1990 Oct 20;215(4):489-92. doi: 10.1016/S0022-2836(05)80161-5.

Abstract

The Fab from an IgG1, lambda murine monoclonal antibody with specificity for the O-polysaccharide antigen of Salmonella typhimurium has been crystallized in the absence and presence of hapten. The conditions for crystal growth were vapor diffusion equilibration with 16 to 23% polyethylene glycol 8000 solutions. Data have been collected from crystals of the complex in space group P212121, a = 60.6 A, b = 111.3 A, c = 61.1 A, and refinement of a molecular replacement solution is underway.
