Growing, titering, and purifying viruses from a variety of species.

High-Titer Virus Production

Our highly specialized team has extensive knowledge and skill in making both wild type and recombinant viruses. Below are just a few examples of the viruses we have in our vast library of biomaterials. We can also help source additional virus species of interest if needed, or if you already have your own strain, we can help you securely send it to us.


  • Adenovirus
  • Influenza A & B
  • Herpes
  • Phage
  • Polio
  • Respiratory Syncytial Virus
  • Rhinovirus
  • SARS CoV-2
  • Varicella-Zoster Virus

Reverse Genetics

For drug discovery projects where mutations in viral polymerases or other viral genes are required for study, Microbiologics offers reverse genetics services. Using molecular biology techniques, reverse genetics enables production of viruses with intentional changes to existing genes, such as desired mutations. It also enables deletion of all or part of a viral gene, or addition of genes not normally found in the viruses. For example, a BSL-2 virus can be engineered to express glycoproteins from other viruses, including BSL-3 and BSL-4 viruses. Our team has experience developing reverse genetics systems for Influenza A and B, Vesicular stomatitis virus (VSV) and SARS-CoV-2.
