The next generation of protein interaction assays

“Next Interaction’s NGIS screening with mutant and wild-type version of a gene implicated in hearing disorders revealed distinct interactions that may underlie observed phenotypes. These initial findings were crucial to our current research.”
Nicolas Grillet, Ph.D., Assistant Professor, Stanford University, USA
“With Next Interactions we were able to map candidate interactors to a novel protein epitope, allowing us to reach pivotal conclusions for our project. Great customer care and turnaround!”
Gregor Andelfinger, MD, FRCPC, Université of Montréal, Canada
“Next Interactions is the ideal partner in molecular engineering and screening of synthetic proteins.  This is an excellent team with such dedication, knowledge and enthusiasm.“
Shuguang Zhang, Ph.D., Massachusetts Institute of Technology, USA

Next Generation Interaction Screening (NGIS) Services for Protein-Protein Interactions

Protein-protein interactions fundamentally underlie the function of biological systems.  Measuring protein-protein interactions is central to understanding the biological basis of disease and for enabling biotechnology to produce products ranging from safer and more effective therapeutics to next-generation foods, materials, and fuels.

Next Interactions, Inc. is a proteomics services company that delivers more complete, sensitive, and precise measurements of protein-protein interactions.  We have developed a Next Generation Sequencing-Yeast Two Hybrid (NGS-Y2H) technology platform that combines the latest innovations in sequencing, yeast-based protein interaction mapping techniques, and quantitative cell-based reporters.

Using cloud-based data delivery, our quantitative protein-protein interaction screens give scientists information-rich data sets with visualizations and bioinformatics analyses that are clear and actionable.

We offer a variety of protein interactome discovery solutions, including parallel interaction fingerprints, comparative interaction profiles, and complete screening of protein variants and mutational profiles of proteins, in addition to the construction and use of custom cDNA libraries for our clients.

Protein Interaction Screening Challenges

Understanding protein interactions can be powerful, but protein interaction screens need to be improved.
