Orthopoxvirus Purification for High Containment Laboratories.

Purification of large viruses in a high containment laboratory can create unique challenges. Traditional purification methods for large viruses rely on equipment and techniques that are not ideal for high containment work. Poxvirus purification has long relied on the use of Genetron®, a reagent that is no longer available. Here we describe a purification protocol that is effective for semi-purification of orthopoxviruses and suitable for work in high containment laboratories.
