After agarose gel purification of cry2Al1 insert it was cloned into the EcoRI/HindIII site of E. coli expression vector pET-22b to get the recombinant plasmid pET22b-cry2Al1. Then ligated pET-cry2Al1 vector was transferred into E. coli BL21 (DE3) pLysS. The clones that had grown on antibiotic medium were considered as transformed clones. The recombinant clone contain- ing pET22b—cry2Al1 recombinant vector was further confirmed by the PCR and restriction digestion. PCR amplification with cry2Aa
