Protein-protein interactions fundamentally underlie the function of biological systems.

What is a protein-protein interaction or PPI?

Protein–protein interactions are the physical contacts of high specificity established between two or more protein molecules.

Why measuring protein-protein interactions matters? 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.  Our Next Generation Interaction Screening and Mapping platform technology (NGIS) combines yeast two hybrid with next generation sequencing  (NGS-Y2H), bringing conventional yeast two hybrid to the level of mass spectrometry approach. Our NGIS platform integrates 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.

Our goal is to bring the most reliable and comprehensive tool to answer your protein interactions questions, whether screening for novel protein interactions for basic research or in search of a new drug target, or precision mapping of known functional interactions, or compound screening. Ultimately, we accelerate the R&D process for you, save you time & money and get you the results you need. 

Protein Interaction Screening Challenges

Understanding protein interactions can be powerful, but conventional protein interaction screens needed to be improved. Why? 

incomplete coverage puzzle

Interaction Coverage

Complete coverage of the interaction space requires analyzing thousands of interaction pairs.

quantitation statistical chart

Quantitation

Quantitative measurements are needed to assess the significance of the results.

precision target

Precision

Conventional Y2H results in too many false positives. Repetition of screens and background controls for statistical rigor reduces false positives.

data visualization on report and screen

Data Visualization

Effective visualization is required to analyze quantitative and comprehensive results.

Consult our Protein Interaction Screening Experts.

Contact Next Interactions for advice from our scientists about the best approach for elucidating the protein interactions you need to understand for your research. We can advise you on methods such as the NGS-yeast two-hybrid system, yeast two-hybrid system, how to compliment interactome coverage by mass spectrometry, and more.
