title: Simplified assay for concanavalin A-dependent bacterial agglutination by using cell surface mutants.
abstract: Two cell surface mutants of Escherichia coli isolated through supersensitivity to sodium dodecyl sulfate were found to be agglutinated by concanavalin A in the intact rod form. By using these strains, the assay method for the concanavalin A-dependent agglutination was greatly simplified since neither spheroplast formation nor protease treatment is needed. This rod cell agglutination was characterized and applied for a semiquantitative determination of the amount of bound concanavalin A.
