Objective To optimize the experimental conditions for single cell gel electrophoresis assay(SCGE).
Methods Orthogonal experiment(4 factors×3 levels)were carried out: unwinding time, gel layer number, electrophor esis time, and electrophoresis voltage.
Results Unwinding time was the main factor, followed by the gel layer number, electrophoresis time, and electro phoresis voltage.Furthermore, number one level under four factors was optimum level.
Conclusion Optimized experimental conditions consisted of 20-minute unwinding time, gel of 3 layers, 20-minute electrophoresis time, and 20 volt electrophoresis voltages.
