Multi-bioinsecticidal-toxin BtA is a bioconjugation product with multiple acting-sites, formed by biochemical bond-linking reaction between two biotoxins, protoxin of Bacillus thuringiensis and Abamectin, through the amino and carboxyl conjugator EDC. The variation of pest susceptibility to Multi-bioinsecticidal-toxin BtA was evaluated by studying the decline and recovery of susceptibility of Plutella xylostella L.

In this study, the structure sequences of Shiga toxin 2B(stx2B) and Shiga toxin 1B(stx1B) were respectively amplified from EHEC O157:H7 by PCR. stx2B-L-stx1B fusion gene was constructed by a 12 bp linker ligating these two fragments. After digested with restriction endonuclease Nco Ⅰ and EcoR Ⅰ, the fusion gene was orientally inserted into expression vector pET28a.
