Thermo Fisher Scientific Acquires Programmable Dye Platform Pioneer Phitonex        

WALTHAM, Mass., Dec. 31, 2020 /PRNewswire/ —

Thermo Fisher Scientific, the world leader in serving science, today announced it has completed the acquisition of Phitonex, Inc., a Durham, North Carolina-based company that has pioneered a spectral dye platform for high-resolution biology applications designed to accelerate research and development in cell therapy, immuno-oncology and immunology research. Phitonex’s product offering will enable Thermo Fisher to offer greater flow cytometry and imaging multiplexing capabilities to meet evolving customer needs in protein and cell analysis research.
The innovative platform, called the “Phiton,” acts as a structure that can maintain a higher number of fluorescent dyes in very specific ways, allowing researchers the ability to analyze single cells in high resolution. Consequently, it enables researchers to achieve deeper biological insights and more comprehensive data from their cell samples. With the ability to rapidly create a multitude of different dye labels, research teams can significantly increase the number of proteins and cell populations that can be identified in a single flow cytometry experiment.
“Phitonex’s platform is a natural extension of Thermo Fisher’s existing tools for protein and cell analysis applications,” said Peter Silvester, senior vice president and president life sciences solutions at Thermo Fisher Scientific. “Combining this new technology with our existing portfolio and expertise in this space will unlock the Phitonex platform’s great potential and deliver unparalleled flow cytometry performance so our customers can gain more valuable insights from a single cell and expedite discovery.”

We are the guiding light that enables illumination of the unknown.

Our team lives and implements our purpose and values by:

Acting as the guiding light in all things related to our work, including building and maintaining a team that is positive, productive, and fun yet rigorous

Enabling and accelerating life science and discovery in ways previously thought impossible.

About Phitonex

Phitonex, Inc. is bringing a new way of thinking about fluorescence and experimental design to the life science laboratory. We will transform the way light is used in life science with a first focus on single cells, the fundamental unit of health and disease.

We have developed a platform that allows us to deterministically engineer optical properties to provide high resolution analysis of single cells by flow cytometry, and in the future, other applications. Lower noise, less spectral overlap, and fluorescence-by-design means that our dyes immediately unlock a higher number of parameters across current instrumentation and provide unmatched cell population resolution to drive enhanced biological insight.

We are also the first team to develop, design, and validate spectral dyes.

The best workplace in the world is:
A crazy good team
achieving the
seemingly impossible

That is what we have built and continue to build at Phitonex. If this sounds like something you want to be a part of, please reach out.

Our Core Values

Full stack thinking + doing

Unafraid to leap

Dogmatically constructive

Balance speed + intentionality
