Assessment of poly-L-lysine dendrigrafts for virus concentration in water: use of MS2 bacteriophage as proof of concept.

Aims: Virus detection has often been difficult due to a low concentration in water. In this study, we developed a new procedure based on concentration of virus particles on an innovative support: poly-L-lysine dendrigrafts (DGL), coupled with directed nucleic acid extraction and real-time PCR quantification.

Methods And Results: This method was evaluated using the bacteriophage MS2 as a model virus.
