ABSTRACT:
The invention concerns a method for purifying a crude viral preparation containing viral, in particular adenoviral, particles of interest. The invention is characterised in that it comprises a step of adsorption on a fluidised bed. The invention also concerns a protocol for producing viral particles for use in gene therapy comprising such a purifying process.
