Bioimaging of geographically adjacent proteins in a single cell by quantum dot‐based fluorescent resonance energy transfer

14 Oct 2009

Abstract excerpt

Thousands of proteins are simultaneously involved in the maintenance of a single cancer cell. Fluorescent resonance energy transfer (FRET) is one of the most general techniques for imaging biologically interacting molecules in a cell. Here, we applied FRET to image the co-localization of two proteins that do not interact biologically (nucleolin and integrin α(v) β(3),) both of which are highly expressed in the...
