The plaque assay remains to be the most widely used technique for virus isolation and purification, and to determine viral titers. The basis of the technique is to measure the ability of a single infectious virus to form a “plaque” on a confluent monolayer culture of cells.

One of the most important procedures in virology is measuring the virus titer – the concentration of viruses in a sample. A widely used approach for determining the quantity of infectious virus is the plaque assay.

Nonetheless, for diagnostic purposes, a rapid, specific and sensitive virus PCR is preferable. Therefore, two independent yellow fever virus-specific real-time PCR assays were established and compared the viral RNA loads to the results of a traditional plaque assay.

A sensitive and quantitative assay system is described for plaquing Modoc virus in Vero cells. Neutralizing antibodies to Modoc virus could be detected by using this in vitro system by their interference with viral plaque formation.

Plaque Assay Method no. 1 ... I have generally found that plaques form better using Grace's medium and serum. Though this is certainly open for debate, here is a method that I use. There are many ways for virus to hide, and so this assay is usually an underestimate of the actual number of virus present.
