RESUMO
The baculovirus expression vector p36C was used to express in cells of the insect Spodoptera frugiperda fragment C of tetanus toxin under the control of the strong polyhedrin promoter. Fragment C was expressed intracellularly at a high level and was soluble, allowing it to be purified by affinity chromatography with monoclonal antibody TT08. Purified fragment C from baculovirus was used to immunize mice and was shown to successfully prevent the symptoms of tetanus following a toxin challenge. The ganglioside-binding properties of baculovirus-derived fragment C were compared with those of intact tetanus toxin and native fragment C and were found to be dissimilar.
