In Situ Binding Assay of Virus-Host Interaction Analysis


In Situ Binding Assay of Virus-Host Interactions

Viruses are obligate intracellular parasites that have co-evolved with their hosts for millions of years, and their life activities depend on the close interactions with host cells. After the virus recognizes the target cell, it begins to use its specialized intracellular environment to replicate, this process affects cell function and may cause disease. Therefore, the study of virus-host interaction is essential for understanding these disease states and developing effective treatments.

Currently, there are many methods that can be used for virus-host interaction analysis to help us explore the interaction network, but what we need to know is that no matter which method, there are limitations in a specific environment. Therefore, it is necessary to combine multiple methods for the study of these interactions. Before designing an experiment, we should fully understand the nature of the experiment and conduct a comprehensive analysis.


In contrast to ex situ binding assays, in situ assays are measured in cells, so the number of artificial interactions is limited, and the modification on the protein may be closer to the state during infection. Creative Proteomics offers a variety of in situ binding assays, including but not limited to affinity purification-mass spectrometry (AP-MS) and proximity-dependent labeling (PDL).

We offer multiple types of AP-MS, including tandem AP-MS, native AP-MS, GFP tagged AP-MS, etc., and the biotinylation based BioID system.
