【Abstract】 Based on the standard procedure of polyacrylamide gel electrophotesis set by IST A for the analysis of the gliadin of wheat and barley seed for the varie ty identification,we screened the main influence factors which would affect the electrophoresis,and tried to improve them to get the best combination.Accordi ng to the results,we established an optimal procedure,it had the buffer system o f Sodium Hydroxide-Acetic Acid-Glycine,and the voltage of electrophoresis sho uld be lower at beginning,then higher for a while,and lower in the end.This m ethod had the properties of high resolution and stability,using less samples,a nd the gel can be easily desquamated than the other methods.Furthermore,this m ethod is easily to operate,more economical,and spend less time than the standa rd procedures,so it can be used in many laboratories to study the gliadin of wh eat.更多还原
