Sažetak
Applicability of electrophoretic separations of albumins/globulins, followed by nonspecific protein staining and specific glycoprotein and aminopeptidase detection has been examined for barley variety discrimination. Albumins/globulins extracted from dry grains and green malt of six barley varieties were separated by polyacrylamide gel electrophoresis (10 % T, pH=8.9) of native and sodium dodecyl sulfate denatured proteins, and by isoelectric focusing in pH gradient of 3.5-9.5 and 4.0-6.5. Analysis of dry grain extracts gave better results than green malt extracts. Obtained data indicate that SDS-PAGE of albumins/globulins and IEF in pH gradient 3.5-9.5 followed by Coomassie Blue staining could be useful in Croatian barley variety discrimination. Angora barley could be clearly distinguished from the other varieties which were grouped as follows: Rodnik/Sladoran, Barun/Rex, and Martin. Glycoprotein patterns did not improve the recognition of individual varieties. Broad specificity, phenylalanine and leucine preferring, and arginine specific aminopeptidase were not found as applicable markers for discrimination of examined barley varieties.
