Question 17

Green fluorescent protein (GFP) can be used to fluorescently label a specific protein in cells by genetically engineering cells to synthesize the target protein fused to GFP. What is the advantage of using GFP fusions to visualize specific proteins, instead of staining cells with fluorescently labelled probes that bind to the target protein?

Accepted Answer

A)  GFP fusions enable one to track changes in the location of the protein in living cells; staining usually requires preserved cells.
