RESUMO
Objective To compare the separation effects of protein samples extracted by two different methods with two -dimensional gel electrophoresis (2-DE) .Methods Ultrasonic disruption and glass-beads grounding were used to prepare protein samples of Gram-negative bacteria , Gram-positive bacteria and animal tissues .The actual results of the two sample preparation methods were compared by 2-DE.Results The 2-DE maps of samples extracted by the two methods were obtained.Conclusion The 2-DE maps of glass-beads grounding samples are better than those of ultrasonic disruption thanks to their lower backgrounds , which are beneficial for further image analyses .
