Bimolecular Fluorescence Complementation as a Tool to Study Specific Dynamic Interactions Between Proteins in Fission...

Bimolecular fluorescence complementation (BiFC) is a technique that enables real-time observation within living cells of the interaction between two proteins forming a complex, determining the location where such interaction occurs within the cell, and even the association and dissociation cycles in response to physiological cues. Here, we describe in detail the use of bimolecular fluorescence complementation to visualize the assembly and disassembly of cohesin over the fission yeast cell cycle.
