Plaque Assay for Influenza Virus
The plaque assay is a widely used approach for purifying a clonal population of virus and determining the viral titers (the lowest concentration of virus that results in infection). This video shows the procedure of plaque assay for influenza virus.

Covalently Closed Circular DNA (cccDNA) Isolation
cccDNA (covalently closed circular DNA) is a crucial intermediate that arises in the cell nucleus during the propagation of hepadnaviruses. It may permit the persistence of virus infection. This video shows you how to isolation cccDNA form infected cells.

Lentivirus is a genus of slow viruses of the Retroviridae family that have long incubation periods and cause chronic, progressive, often fatal diseases affecting many organs in humans. This video shows you how to infect culture cells with lentivirus. It is an important step before the production of lentiviral vector.

Competent cells are those that possess more easily altered cell walls that DNA can be passed through easily. Because DNA is hydrophilic, it will not normally pass through membrane. In order to make these cells readily incorporate foreign DNA, they must first be made "competent" to take up foreign DNA.
