Abstract

The aim of this work was to obtain the panel of recombinant single-chain Fv-antibodies against diphtheria toxin B subunit, the main diagnostic and pathogenic antigen of Corynebacterium diph-theriae. For this purpose we have constructed the immune library of murine immunoglobulin genes.A number of scFv specific to diphtheria toxin B subunit were acquired from the obtained library after one round of selection by phage-display. ScFv encoding DNA-fragments of eight clones were subcloned into plasmid pET-22b(+). It was shown that selected scFv were highly specific to diphtheria toxin B subunit, with affinity constant for different clones ranged from 10 7 to 10 9 M -1.
