Creative Biolabs has a highly skilled analytical team capable of performing a wide range of assays. To meet our customers' needs, we developed the Median Tissue Culture Infectious Dose (TCID50) assay to determine the viral titer of a testing virus. Our team will collaborate with you to identify and develop qualified assays to meet the needs of your specific project.
The measurement of virus titer is one of the most important procedures in virology. Plaque assay is the most practical method and the gold standard for determining infectious viral titer. However, many viruses do not form traditional plaques, and tools for determining viral foci via immunolabeling or fluorescent reporters may not be readily available. The TCID50 assay is used to determine viral titers by determining the concentration at which 50% of infected cells exhibit cytopathic effect (CPE). Cell rounding, fusing, and other morphological changes are phenotypically indicative of CPE. This method is also used for viruses that are not cytopathogenic or do not form plaques. As a result, the TCID50 assay can be used to assess the infectious titer of any such virus.
Creative Biolabs offers TCID50 assay services with high sensitivity and accuracy. Assays can be selected and tailored to your specific concerns and requirements, ensuring that an appropriate testing plan is developed for your project.
The TCID50 assay workflow is as follows:
