Besides molecular analyses at the DNA and RNA level, it is also necessary to determine whether the introduced transgene
is translated to the intended Cry1Ac protein product. Accord-ingly, the accumulation of the novel Cry1Ac protein in the
developed transgenic plants was demonstrated by an immuno-strip assay specific to Cry1Ac/Cry1Ab proteins. A similar tech-nique was used to detect the presence of Cry1Ab protein intransgenic potato and three Cry proteins (Cry1Ac, Cry2Ab and Cry1F) in transgenic cotton genotypes
