Popis: In this paper we describe the engineering and regeneration of transgenic tobacco plants expressing a recombinant plasma membrane-retained antibody specific to microcystin-LR (MC-LR), the environmental toxin pollutant produced by cyanobacteria. The antibody was created by a genetic fusion of the antigen binding regions of the microcystin-specific single chain antibody, 3A8, with the constant regions from the murine IgG1κ, Guy's 13, including a membrane retention sequence at the C-terminal end of the antibody heavy chain. The antibody produced in the leaves was shown to be functional by binding to MC-LR in an ELISA with antibody yields in transgenic plant leaves reaching a maximum of 1.2 μg g(-1) leaf f.wt (0.005% total soluble protein). Antibody-MC-LR complexes formed in leaves after addition of MC-LR to hydroponic medium around the roots of transgenic plant cultures.
