Protein Interaction Analysis Services


Protein-protein interactions (PPIs) are established when protein molecules physically contact with each other through hydrogen or hydrophobic bonds, Van der Waals forces, ionic forces, or even covalent bonds. This phenomenon underlies a wide range of essential cellular events such as signal transduction, molecular transport and various metabolism pathways. PPIs are also the basic of many diseases. Therefore, PPIs have been studied extensively in the area of bioscience and medical research.

Protein Interaction Analysis Services

Profacgen has organized a team of scientists with extensive experience in the study of PPIs to offer you one-stop service on your PPI project. We can help with your experiment design, carry out your experiments, and perform data analysis. We have established in our lab a series of assays to help with your research, including high throughput interaction screening assays such as Yeast two-hybrid screening and phage display technology, interaction strength and kinetics assays such as Surface Plasmon Resonance (SPR). Each approach has its own advantages and weaknesses in terms of sensitivity and specificity. While you can choose the techniques you prefer, we can also help recommend.

Please see below the list of assays we can do for you:

Yeast Two-Hybrid Screening
Membrane-based Yeast Two-Hybrid Screening
Phage Display Technology
Surface Plasmon Resonance (SPR)
Fluorescence Resonance Energy Transfer (FRET)
Protein Array
Co-Immunoprecipitation (Co-IP)
Pull-Downs
Biomolecular Fluorescence Complementation (BiFC)
Bio-layer Interferometry (BLI)

Please feel free to contact us with your protein-protein interaction projects. Profacgen is here to offer you professional and thoughtful service!
