Fig 2

(A1) Normalized fluorescence data for VSD assay on A2R-stg cells with 50 μM fluorowillardiine (black) with maxGLU (red) and NBQX (pink) controls, all normalized to EC50GLU (blue). (A2) CRC curves for FW against A2-stg and (A3) A2-C3 cell lines calculated from the CMPDslope window. %max GLUslope = (CMPDslope—mean VHLslope)/(mean maxGLUslope—mean VHLslope) is further described in methods. (B1) Normalized fluorescence data for VSD assay on A2R-stg cells with 1 mM CX-546 (black) with maxGLU (red) and NBQX (pink) controls, all normalized to EC50GLU (blue). (B2) CRC curves for CX-546 against A2R-stg and (B3) A2R-C3 cell lines calculated from the GLUslope window. %max GLUslope = (GLUslope—mean VHLslope)/(mean maxGLUslope—mean VHLslope) (C1) Normalized fluorescence data for VSD assay on A2R-stg cells with 500 μM cyclothiazide (CTZ, black) with maxGLU (red) and NBQX (pink), all normalized to EC50GLU (blue). (C2) CRC curves for CTZ against A2-stg and (C3) A2-C3 cell lines calculated from the GLUslope window. Compound EC50 values that could be reliably calculated are in the top left corner of each graph.
