Genetic Engineering & Biotechnology News is out with a Feature Article this week including some comments from David Drubin about targeted genome modification in mammalian cells for fluorescence microscopy studies.

“The difference between taking snapshots of the process and watching a movie is just night and day,” says David Drubin, Ph.D., professor of cell and developmental biology at the University of California, Berkeley, whose lab uses fluorescence to understand the intricate details underlying clathrin-mediated endocytosis.
Researchers in David Drubin’s lab at the University of California, Berkeley genetically engineered a human cell line to express endogenous levels of RFP-tagged clathrin light chain A (red) and GFP-tagged dynamin 2 (green) for studying clathrin-mediated endocytosis. The above 3D kymograph of the cell surface, with the time dimension in the z-axis, shows the full lifetime of hundreds of clathrin patches on the membrane, which terminate upon recruitment of dynamin.
