EEV Systems

An easy-to-produce non-integrating option for gene expression that can deliver sustained expression from a non-viral system

With virtually no limits on insert size (unlike AAV vectors) Enhanced Episomal Vectors (EEVs) are an excellent choice for non-integrating, non-viral gene expression. Because they replicate in synchrony with the host cell, they are stably inherited and can be used for long-lasting expression—up to several months both in vitro and in vivo—without modifying the host genome.

Comes in both constitutive and inducible gene expression formats.
