Web13 feb. 2012 · Background In the biological sciences the TCID50 (median tissue culture infective dose) assay is often used to determine the strength of a virus. Methods When the so-called Spearman-Kaerber calculation is used, the ratio between the pfu (the number of plaque forming units, the effective number of virus particles) and the TCID50, … WebLOD units. Copies/ml — number of copies of viral RNA detected per milliliter of sample.; TCID50/ml — represents the “Median Tissue Culture Infectious Dose” per milliliter of sample, and is used to verify viral titer. TCID50 signifies the concentration at which 50% of the cells are infected when the sample is inoculated with a diluted solution of viral fluid.
