Viruses, most notably Baculovirus, are used to produce complex eukaryotic proteins in an appropriate host cell system. These recombinant proteins have been used in research and as vaccines in both human and veterinary medical treatments. For example, the most widely used vaccine for prevention of H5N1 avian influenza in chickens was produced in a Baculovirus expression vector. The generation and amplification of viruses used for protein expression is dramatically streamlined by the ability to monitor virus particle concentrations in essentially real time using the Virus Counter 3100. To learn more, email us at


“We have basically stopped running plaque assays on our P0 and P1 virus stocks because the accuracy of the titers obtained with the Virus Counter leads to better virus amplifications than those obtained using plaque assay titers. The instrument saves one to two weeks on our virus production timeline and it is very helpful to know within a day or two that a transfection or co-transfection has yielded virus particles.”
