Fluorescence Microscopy Technique Provides New Views Of Biological Processes

Fluorescence microscopy has long been a powerful tool in biological research. A form known as total internal reflection fluorescence (TIRF) microscopy has more recently been used to watch biological processes unfold in real time. By taking advantage of the ability to label individual molecules with different colors of fluorescent tags, TIRF microscopy now affords scientists a view into the complex molecular assemblies that govern cellular processes.
