It has a small genome of 5243 bp and utilizes cellular proteins for its molecular biology, with the exception of the T-antigen protein, which is coded by the virus and is involved in regulating transcription and directing replication. Importantly, SV40 exists as chromatin in both the virus particle and intracellular minichromosomes. These facts, combined with high yields of virus and minichromosomes following infection and ease of manipulation, have made SV40 an extremely useful model to study all aspects of eukaryotic molecular biology. This unit describes procedures for working with SV40 and preparing SV40 chromatin from infected cells and virus particles, as well as procedures for using SV40 chromatin to study epigenetic regulation.en-USPublisher PolicySimian virus 40 (SV40)Chromatin immunoprecipitationMinichromosomesNext-generation sequencingViral epigeneticsArticle
