VLX®
The MaxCyte VLX® Scalable Transfection System is a bench-top, easy-to-use instrument specifically designed for extremely large volume cell-engineering. Using proprietary Flow Electroporation™ Technology, the MaxCyte VLX can transfect up to 200 billion cells in less than 30 minutes – 10x the capacity of the MaxCyte STX®. This cGMP-compliant system offers a clear regulatory pathway and is ideal for the rapid production of recombinant proteins, monoclonal antibodies, viral vectors, vaccines and VLPs from R&D through cGMP pilots and commercial manufacturing.

Duplicate sets of 2E10 CHO-S cells were transfected with an hIgG1 expression plasmid (1ug/1×106 cells) via flow EP with the STX or the VLX. Transfected cells were seeded into 1 L cultures at a starting density of 4E6 cells/mL, and fed batch cultures were maintained for 15 days. Secreted protein titers were monitored by ELISA; cells counts and viabilities were measured via trypan blue staining. Error bars denote standard deviations from three replicate shake flasks.
