WebDocument: Tenfold dilutions of the virus were used to inoculate MDCK cells in a 96-well plate, and infected cells were maintained in culture for 72 h. Viral titers were calculated using the Reed-Muench method and are expressed as the tissue culture infectious dose (TCID50) per milliliter of supernatant. WebThis calculation can generally be done by a variety of mathematical approaches, e.g., the Spearman-Karber method or the Reed-Muench method. Virus titer is expressed as TCID 50 / ml. Other biological assays are available
