Capillary electrophoretic profiling of tryptic digests of water soluble proteins from Bacillus thuringiensis-transgenic and non-transgenic maize species

► Protein digests of maize species were separated by capillary electrophoresis (CE). ► Each of three maize species provided specific CE-UV profile of tryptic peptide map. ► CE-UV tryptic peptide maps of proteins may be used to differentiate maize species.
