Nanoparticles aid microscopic detection of protein relevant for cancer

Assemblies of proteins have important functions in cells. But because they are very small, their composition from subunits can only be determined indirectly or with extreme time-effort. Scientists are currently developing a novel microscopy technology for the direct detection of such individual subunits of protein complexes in the cell membrane of intact cells. The methodology is applied to investigate a protein complex acting as a calcium channel in the cell membrane. The channel plays an important role in prostate cancer.
