Measuring Immune Receptor Mobility by Fluorescence Recovery After Photobleaching

The coordinated effort of cells in the immune system relies heavily on surface receptor interactions. Immune receptor mobility provides vital information on the function and responses of immune cells, and these measurements shed light on their interactions with other membrane, cytosolic, and extracellular matrix proteins. These measurements can be obtained using the fluorescence recovery after photobleaching (FRAP) technique in living cells. We describe here general approaches for FRAP using green fluorescent protein fusion proteins.
