For your more complex cell line projects, trust ExpressCells as your outsourced gene editing company when in-house is not an option. We are faster than our competitors, saving you time and money.

Quite simply, we can do what others cannot.

ExpressCells’ founder, Oscar Perez-Leal, has published a new case study of our gene-edited cell lines in Biomolecules

Did you miss our October webinar on Gene Editing?

You can watch it on-demand here!

What You’ll Learn:

  • Understand the current challenges in creating custom gene-edited cell lines
  • Know the technology underlying the FAST-HDR gene-editing system, including its use with CRISPR
  • Be able to describe the advantages of the FAST-HDR system
  • Learn about several case studies using gene-edited cell lines

Improve your research. ExpressCells uses CRISPR and its patented plasmid system to create knock-in cell lines that fit your experiments.

  • Cell lines delivered 2-3 months faster than competing knock-in technologies

  • Up to 3 genes inserted in the same cell

  • Your choice of tagging, overexpression models, and point mutations. We can mix the types of knock-ins in the same cell.

  • We control quality by making each cell line in our own labs in Philadelphia, PA, USA

"The ExpressCells CRISPR-edited cell line contributed greatly to our COVID-19 related work and will eventually lead to a publication. Not only did ExpressCells deliver the cells quickly, the CRISPR-edited cell pool exhibited such high level overexpression that a clonal cell line was not required. We appreciate the quality of ExpressCells' work and their team's responsiveness."


Aaron Sato, PhD, Chief Scientific Officer, Twist Biosciences

"I will be happy to work with ExpressCells again. We have plans for using this type of cell in many experiments and will use ExpressCells for our future projects."
