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.
