Scientific Reports
Sodium valproate/valproic acid (VPA), a histone deacetylase inhibitor, and 5-aza-2-deoxycytidine (5-aza-CdR), a DNA methyltransferase 1 (DNMT1) inhibitor, induce DNA demethylation in several cell types. In HeLa cells, although VPA leads to decreased

Rapid detection of infectious rotavirus group A using a molecular beacon assay
Autor: Maria Silvia Viccari Gatti, Jéssica Wildgrube Bertol
Publikováno v: Journal of Virological Methods. 234:156-159
Rapid, sensitive and specific methods are necessary to detect and quantify infectious viruses. Cultivating and detecting enteric viruses in cell culture are difficult, thus impairing the advancement of knowledge regarding virus-induced diarrhea. Rota
