title: End-point dilution and plaque assay methods for titration of cricket paralysis virus in cultured Drosophila cells.
abstract: Cricket paralysis virus, an insect picorna-like virus, caused a distinct c.p.e. in cultured Drosophila melanogaster cells, allowing the development of titration methods based on end-point dilution or plaque assay methods. The end-point dilution (TCD50) method is more sensitive and economical than plaque assays and is easily scored. The data indicate a minimum infectivity/particle ratio of about 1/2000.
