ProBioGen Launches Lentivirus Packaging Cell Line

ProBioGen, a Berlin-based company specializing in the development and manufacture of APIs, announced its new lentivirus packaging cell line on May 17, 2023. Lenti.RiGHT is a lentivirus production platform based on human embryonic kidney 293 packaging cells.

According to a company press release, the new line is capable of producing lentiviral particles with titers between 107 and 108 transducing units per mL. It includes stable integration of gag-pol, rev, and vesicular stomatitis virus-G proteins.

"With our Lenti.RiGHT platform we have developed a new standard for efficient large-scale lentivirus production and CAR–T [chimeric antigen receptor T cell] manufacturing,” said Volker Sandig, chief scientific officer, ProBioGen, in the release. “It enables an inducible, scalable, and efficient production of high-titer lentiviral particles for gene transfer applications.”
