Virus Quantification Using the Virus Counter

A wide variety of viruses have been successfully analyzed by the Virus Counter. These include virus samples from commercial sources as well as those supplied by collaborators from fields including vaccine development, antigen production and medical research.  The table below summarizes the diversity of virus samples that have been successfully analyzed. These include several hundred collaborator-supplied samples of influenza from a number of propagation sources in a variety of real-world suspension buffers and matrices.
