I would like to use EBER PNA Probe/Fluorescein kit from Dako (Y5200) for flow cytometric analysis of EBV virus presence in our cell lines and patients samples. I have found a protocol, unfortunatelly, I don´t know the exact concentration of each of PNA probes contained in the stock solution and, therefore, I don´t know what volume of PNA probes I should use. Thank you for help. Petr
