The fast and effortless generation of stable cell lines for protein production significantly optimizes yield, product quality and processing costs.

Mammalian cell lines are commonly used for mammalian protein production. Current expression systems are based on either transient or stable transfection of the gene of interest.

Cell line engineering is an efficient way to reduce time and effort for developing a master producer cell line: increasing yield and stability of expression even in the absence of selection agents, increasing the half life of your cell line, increasing final product quality and reducing purification processes.

Cellectis bioresearch offers cell line engineering services to knock-out specific genes or easily re-target a transcriptionally active protein production hotspot in a Research or GMP compliant environment.

We also provide a cGPS® Targeted Integration kit dedicated to protein production applications: cGPS® CHO-Sa CEMAX®.
