AAV-titers for different serotypes before process optimization, obtained by standard transient, PEI-mediated transfection of CAP-GT cells with corresponding 2-plasmid system (PlasmidFactory) and electron microscopic image of AAV2 particles produced with CAP-GT cells (courtesy of Paragon Bioservices).


CAP-GT suspension cells efficiently produce adeno-associated virus (AAV) vectors of different serotypes. CAP-GT-derived AAV particles display an excellent full vs. emtpy ratio.

Rapid, high quality production of AAV vectors is achieved for example using the 2-plasmid system of PlasmidFactory.

PEI mediated transfection efficiencies and corresponding lentiviral vector titers in CAP-T and adherent HEK293T cells.


Using suspension CAP-T cells from the CAP-GT platform, high titers for HIV-1 based lentiviral vectors are reached, outperforming adherent HEK293T cells.

The CAP cell line produces 5.000-10.000 infectious adenovirus particles per cell. No undesired replication competent adenovirus (RCA) could be detected in 5x10e10 viral particles (VP) from CAP cells, whereas 5-500 RCAs can be detected in 5x10e10 VP produced in HEK293 cells.


CAP-GT cells are highly suitable for high titer production of replication deficient adenoviral vectors.
