The CTS Xenon Electroporation System is designed to be an easy-to-use system for exceptional, nonviral transfection performance which supports a closed, integrated workflow. Two compatible electroporation accessories allow scaling from process development to commercial manufacturing.

CTS Xenon 1 mL SingleShot electroporation chamber

The CTS SingleShot chamber, designed for process development, can transfect 2–10 x 10⁷ cells in one batch.

Electroporation buffers

We offer three different buffers designed for use with the Xenon Electroporation System. Gibco CTS Xenon Electroporation Buffer is a universal buffer that supports the transfection of a variety of human primary cells and payloads (such as plasmid DNA, mRNA, miRNA, or siRNA) for gene up-regulation or down-regulation applications. Gibco CTS Xenon Genome Editing Buffer is designed specifically to improve performance with gene editing-specific payloads (such as CRISPR-Cas9) for knock-out or knock-in applications in a variety of human primary cells. Gibco CTS Xenon Lower Conductivity Electroporation Buffer is designed for use with cell types that require higher energy electroporation settings to achieve successful transfection.


CTS Xenon buffers are phosphate- and salt-based and contain ions and sugars to control for conductivity and osmolality.


Closed-system compatibility. CTS Xenon buffers are available in 100-mL bottle and 100-mL bag formats for convenient process development and closed-system manufacturing scale-up.

CTS quality. Gibco CTS products follow USP <1043> covering “ancillary materials for cell, gene, and tissue-engineered products” within the responsibilities applicable to a supplier*. The products are supplied with harmonized documentation such as intended use statements, certificates of analysis, and certificates of origin. Regulatory support, such as letters of authorization to reference our drug master file (DMF), are available to assist in your regulatory filing.


Gibco CTS products are of high quality and are manufactured at a site that uses methods and controls that conform to cGMP for medical devices, 21 CFR Part 820 and Ph Eur 5.2.12. Our FDA-registered manufacturing sites are ISO 13485-certified.

Bioprocess automation and control software: Integration of the Xenon system with other Thermo Fisher Scientific products

In cell and gene therapy, “the process is the product,” so perhaps the primary challenges are issues of manufacturing. Autologous T cell therapy, for example, often includes many open processes that are prone to contamination, and many labor-intensive manual manipulations that are prone to errors. Solutions to the first challenge include moving to a closed system, while solutions to the second include automation.


As explained in Features, the Xenon Electroporation System can be physically integrated with other Thermo Fisher Scientific instruments and consumables, such as the CTS Rotea Counterflow Centrifugation System and the CTS DynaCellect Magnetic Separation System, into a complete, closed cell therapy manufacturing workflow.


In addition, these instruments are all digitally connectible with full Open Platform Communications–Unified Architecture (OPC-UA) compatibility. They are designed to be automated and controlled by bioprocess controllers and software compatible with the Emerson’s DeltaV™ Distributed Control Platform, a widely used, well accepted, open system that conveys seamless connectivity to all layers of automation.


Digital integration is especially important when moving from research and process development to GMP manufacturing. Gibco CTS Cellmation software is an off-the-shelf solution designed to help simplify and optimize cell therapy manufacturing processes by providing digital connectivity to Thermo Fisher Scientific’s modular cell therapy instrumentation while enabling 21 CFR Part 11 compliance.
