C inside the imaging medium applying an inverted microscope equipped with an oil immersion objective and an EM-CCD camera or an inverted microscope equipped with an oil immersion objective and cooled CCD camera. Fluorescent signals were detected employing proper filter sets for QD and FM. GABAAR-QD lateral diffusion was recorded with an integration time of ms with consecutive frames. All recordings have been taken within min. Information evaluation for QD-SPT experiments The trajectory of GABAAR-QD was obtained by crosscorrelating photos with a Gaussian model on the point spread function, and diffusion coefficients and confinements have been calculated applying TI workbench computer software written by Dr. T. Inoue, as described previously. Only single QDs identified by intermittent fluorescence were analyzed. The synaptic region was defined by processing FM pictures with wavelet decomposition. GABAAR-QDs had been classified as ��synaptic��when overlapping with synaptic area+ pixels. For the calculation of diffusion parameters within the synapse except for synaptic dwell time, the longest sub-trajectories of single GABAAR-QDs with greater than or equal to points in each compartment were taken into account. To receive the diffusion parameters, such as the diffusion coefficient and confinement size, values of the mean square displacement plot versus time had been calculated for every trajectory by applying the following equation: MSD ~ N{n h X i~ N{n i xiznt{xi t zyiznt{yi t , where t is the acquisition time, N is the total number of frames, and n and i are positive integers with n representing the time increment. Diffusion coefficients were calculated by fitting first four points of the MSD versus time curves with the following equation: MSD~Dn tzb, QD-SPT experiments Neurons were incubated with the custom-made anti-GABAARc antibody for min, washed, and incubated with the biotinylated anti-rabbit Fab antibody for min. Following washes, the coverslips were incubated with . nM streptavidin-coated QDs emitting at nm or nm in borate buffer for where b is a constant reflecting the spot localization accuracy. In this system, GABAAR-QDs with a diffusion coefficient less than . mms were defined as immobile. The confinement domain size, in which the diffusion of GABAAR-QD was restricted, was obtained by fitting the MSDnt plot to the following equation: L Dn t { exp { zDmac n t L MSD~ , where L is the confined area in which diffusion is restricted, and Dmac is the diffusion coefficient on a long time scale. The Gephyrin-Independent GABAAR Dynamics and one-way ANOVA tests, followed by Tukey's posthoc tests. For comparisons between two groups, the MannWhitney U test or Welch's t-test were performed as indicated. All statistical analysis was performed using KaleidaGraph. Images were prepared for printing using MetaMorph, Adobe Photoshop, and Adobe Illustrator. GABAAR XL experiments GABAARs on the cell surface were cross-linked by Foretinib And Renal Cell Carcinoma incubating neurons with the anti-c subunit antibody for min, washing, and incubating with Alexa FluorHconjugated anti-rabbit antibodies for min in the imaging medium. Cells were further incubated with the biotinylated anti-rabbit Fab antibody and streptavidin-coated QDs for QD-SPT, or fixed and subsequently immunolabeled with the gephyrin antibody for quantitative immunocytochemistry, as mentioned previously. In all experiments, it was confirmed that surface GABAARs were successfully cross-linked by fluorescence from GABAAR-associated clusters. Supporting Informatio
