Diffusion of QD-Tagged Receptor in Synapse

This video shows the diffusion of QD (quantum dots)-tagged GABA receptor molecules in a synapse using high-resolution and low-light imaging platforms and Andor iXon EMCCD camera.

QDs and pH-sensitive GFP tags are used to visualize single receptors and to mark receptor clusters at synapses. GABA receptors are a class of receptors that respond to the neurotransmitter gamma-aminobutyric acid.
