Asymmetrical flow field-flow fractionation in purification of an enveloped bacteriophage ϕ6 [PDF]

Journal of Chromatography B, 2018
Basic and applied virus research requires specimens that are purified to high homogeneity. Thus, there is much interest in the efficient production and purification of viruses and their subassemblies. Advances in the production steps have shifted the bottle neck of the process to the purification. Nonetheless, the development of purification techniques
