Application of CGE to virus identification.
Methods in molecular biology (Clifton, N.J.)(2013)
摘要
Protein profiling is an increasingly valuable tool for the characterization of protein populations and has been used to identify microorganisms, most often using two-dimensional gel electrophoresis followed by mass spectrometry. We present a rapid method for the identification of viruses using microfluidic chip gel electrophoresis (CGE) of high-copy number proteins to generate unique protein profiles. Viral proteins are solubilized, fluorescently labeled and then analyzed using the μChemLab™ CGE system (∼10 min overall). A Bayesian classification approach is used to classify the reproducible and visually distinct protein profiles of MS2 bacteriophage, Epstein-Barr, Respiratory Syncytial, and Vaccinia viruses as well as discriminate between closely related T2 and T4 bacteriophage.
