Smallpox A27L Products

Vaccinia virus, a member of Poxviridae family, is a dsDNA enveloped virus. There are two major forms of infectious orthopoxvirus: the intracellular mature virion (IMV), which is infectious when released from disrupted cells, and the extracellular enveloped virion (EEV), which buds from infected cells. A27L is an IMV-specific gene.
