Fluorescence Recovery After Photobleaching (FRAP) is a powerful method for measuring global protein diffusion and has opened new areas of study in molecular and cell biology. In this technique, molecules of interest are fluorescently labeled and a focused laser is used to rapidly and acutely inactivate the fluorescence by photobleaching a small subregion of the cell. Mobile molecules then repopulate the bleached area over time. The rate of recovery provides an accurate measure of the molecular mobility within the cell. Performance of accurate FRAP studies, however, requires paying special attention to preservation of specimen integrity and places special burden on the illumination, optics, and camera so that overall efficiency and speed is optimized.

Attendees at this free online seminar will learn how modern FRAP systems are constructed and utilized to effect accurate, high-speed studies of intracellular diffusion and discuss some of the desired properties of FRAP analysis software.

Subjects include:

Considerations when defining a system for FRAP studies
2D and 3D FRAP applications
Widefield and confocal approaches
FRAP-related studies such as photoactivation and photoconversion (iFRAP)
