ID Plasmid Purpose
158755pAAV-Syn-SomaGCaMP6f1Cell body-targeted GCaMP6f under synapsin promoter: GCaMP6f followed by a linker, the tail region of AnkyrinG, and an ER export motif (GCaMP6f-27-AnkTail-motif-ER2). Not as bright as SomaGCaMP6f2.
158756pAAV-Syn-SomaGCaMP6f2Cell body-targeted GCaMP6f, under synapsin promoter: GCaMP6f followed by a linker, and the EE-RR coiled-coil motif (GCaMP6f-27-EE-RR). As bright as conventional GCaMP6f.
158757pAAV-CAG-SomaGCaMP6f2Cell body-targeted GCaMP6f, under CAG promoter: GCaMP6f followed by a linker, and the EE-RR coiled coil motif (GCaMP6f-27-EE-RR). As bright as conventional GCaMP6f.
158758pAAV-Syn-nullCoChR-GCaMP6f-Kv2.1Cell body-targeted GCaMP6f, under synapsin promoter: nullCoChR (the optogenetic protein CoChR mutated to have 0 current), followed by GCaMP6f and the KV2.1 motif (nullCoChR-GCaMP6f-Kv2.1).
158759pAAV-Syn-SomaGCaMP7Cell body-targeted GCaMP7f, under synapsin promoter: GCaMP7f followed by a linker, and the EE-RR coiled coil motif (GCaMP7f-27-EE-RR). As bright as conventional GCaMP7f.
158760elavl3:SomaGCaMP7fCell body-targeted GCaMP7f, under HuC promoter: GCaMP7f followed by a linker, and the EE-RR coiled coil motif (GCaMP7f-27-EE-RR). As bright as conventional GCaMP7f.
182941pAAV-EF1a-FLEX-SomaGCaMP7Cre-dependent expression of cell body-targeted GCaMP7f, under EF1a promoter. As bright as conventional GCaMP7f.
182942pAAV-CAG-FLEX-SomaGCaMP7Cre-dependent expression of cell body-targeted GCaMP7f, under CAG promoter. As bright as conventional GCaMP7f.
