Dimethyl sulfoxide blocks herpes simplex virus

May 24 2002Dimethyl sulfoxide (DMSO) is frequently used at a concentration of up to 95% in the formulation of antiherpetic agents because of its properties as a skin penetration enhancer Here we have analyzed the effect of DMSO on several parameters of Herpes Simplex Virus replication Productive infection levels of HSV-1 were determined by plaque assay or by reporter gene activity and its DNA

A chemical method for fast and sensitive detection of DNA

We have developed a method to detect DNA synthesis in proliferating cells based on the incorporation of 5-ethynyl-2′-deoxyuridine (EdU) and its subsequent detection by a fluorescent azide through a Cu(I)-catalyzed [3 + 2] cycloaddition reaction ("click" chemistry) Detection of the EdU label is highly sensitive and can be accomplished in minutes
