ABSTRACT
BACKGROUND:
Rabbit serum samples are widely used in basic researches, and two-dimensional gelelectrophoresis (2-DE) is the most classic technique for protein separation. Therefore, it is of great significance to establish a stable technique system of 2-DE for rabbit serum.OBJECTIVE:
To establish a 2-DE technique system for rabbit serum protein separation. DESIGN, TIME ANDSETTING:
A single sample observational experiment was performed at Tianjin Key Laboratory of Biomarkers for Occupational and Environmental Hazard of Chinese People's Armed Police Forces Medical College from June to July in 2008. MATERIALS Six healthy rabbits were provided by the Animal Experimental Center of Tangshan Vocational Technical CollegeMETHODS:
Health rabbit serum was dissolved in rehydration sample loading buffer before and after eliminating high abundance proteins to make proteins in it schizolysis adequately. After reductive alkylation, the samples were loaded into the rehydration tray to undergo passive rehydration for 14 hours. Isoelectric focusing (IEF) electrophoresis was followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). After sliver staining, the gel was analyzed by PDQuest7.4. MAIN OUTCOMEMEASURES:
①Efficiency of eliminating high abundance proteins. ②Two-dimensional eleotrophoregrams (2-D electrophoregrams)RESULTS:
Distinct 2-D eleotrophoregrems were obtained with high resolution and good reproducibility. The removal of high abundance proteins in serum failed to result in better 2-D electrophoregrams.CONCLUSION:
We have successfully established a 2-DE technique for rabbit serum proteome, which can lay the foundation for the further study of serum proteomics of diseases.
