GCaMP2 is expressed in astrocytes and interneurons (A) Astrocytic and neuronal localization of GCaMP2 protein in organotypic cortical slices as shown by colocalization with the astrocyte-specific GFAP and interneuron-specific GAD-67 markers. Cells showing colocalization are marked by arrows. Scale bars: 50 μm. (B) Changes in GCaMP2 and GFAP expression as measured by average intensity within cell ROIs (n = 22–34 cells) in organotypic cortical slices as a function of days in culture (DIV). (C,D) Representative traces (top), I/V plot (middle) and action potential generating ability (bottom) of whole-cell patched GCaMP2 expressing astrocytes (C, n = 30) and neurons (D, n = 7) in organotypic cortical slices.
