Sažetak

The capillary electrophoresis with UV detection was employed for protein profiling in extracts
from maize and soybeans. Modifications of back-ground electrolyte and coating the capillary wall with
polybrene was employed in order to decrease the protein adsorption on the capillary walls. The obtained
protein profiles were compared for transgenic and non-transgenic variants, showing in some cases significant
changes that might be employed for identification of genetic modifications of plants or foods of plant
origin. (doi: 10.5562/cca1777)
