New Dimensions in Confocal Microscopy PerkinElmer's new UltraVIEW RS microscope produces real-time images in six dimensions Courtesy of PerkinElmer A protein's function depends on its movement inside a cell and interactions with other proteins and biological structures. Biologists who want to watch proteins working in living cells frequently turn to confocal microscopy. "Confocal microscopy is critical for modern cell biology and physiology," says Michael Nathanson of the Yale University Sc

Courtesy of Invitrogen Scientists studying a protein's function frequently start with the gene that encodes it. "You want to know what a protein does at the biochemical, cellular, physiological, and organismal levels," says Marc Vidal, assistant professor of genetics at Harvard University and research associate at the Dana-Farber Cancer Institute. "To do that, you need to express this protein under many different conditions using the region of the gene that encodes it, and that's the open read
