More Information
Summary:Disclosed herein is a chemo-proteomic probe for labelling and monitoring a live microbe interacting with a host cell and for qualitative and quantitative analyses of those proteins involved during a microbe infects the host cell. This probe comprises a functional group for conjugating to a surface protein of a live microbe under a physiological condition; a photo-reactive group for covalent cross-linking to an interacting cell protein of a host; and a tag for isolating the cross-linked complex of the surface protein of said live microbe and the interacting protein of a host cell for qualitative and quantitative proteomics analyses. The probe may further comprise a visualization tag. This technology takes advantage of the high throughput feature of mass spectrometry analysis and combines it with a uniquely designed chemistry to achieve high efficient isolation and analysis of host cell proteins interacting with a pathogen at different stages of an infection.
