Patent Summary

Purifying therapeutic proteins like antibodies from samples containing viruses using caprylic acid to inactivate the viruses. The method involves loading the protein-containing sample onto a chromatography column, washing it with a caprylic acid solution, and then eluting the protein. Caprylic acid inactivates viruses like lipid-coat containing viruses and mycoplasmas when used in washing solutions. This allows purifying proteins while simultaneously eliminating contaminating viruses.
