GPEx® Lightning

Published on: 

Catalent’s GPEx® Lightning provides next-generation cell line engineering to accelerate development of biologic molecules.

GPEx® Lightning is built upon Catalent’s existing GPEx cell line development technology, which is an established means of generating genetically stable, high-titer cell lines.

Leveraging the GPEx expression platform in a glutamine synthase (GS) knock-out Chinese hamster ovary (CHO) cell line system, GPEx Lightning combines innovative solutions, including a novel gene insertion technology, to further shorten drug substance development by up to three months compared to previous timelines.
