Separation techniques may offer interesting alternatives to classical virological techniques both for fundamental research purposes and for vaccine manufacturing. A capillary electrophoretic method for the analysis of the poliovirus was developed based on conditions for the human rhinovirus taken from literature. The method was optimized using a 12-experiment Plackett-Burman design, applied in order to examine simultaneously the effects of eight factors on responses such as, mobility of the electroosmotic flow, effective mobility of the poliovirus, analysis time and resolution between the virus peak and a system peak. The proposed method manages to perform an acceptable separation of poliovirus particles using a 50 mM berate buffer with 25 mM SDS, in an uncoated fused-silica capillary upon application of 10 W at 30 degrees C. The linearity of the proposed method was investigated for a range of poliovirus dilutions up to 140 mu g/mL. (C) 2008 Elsevier B.V. All rights reserved.
