Figure 1. Immunofluorescence analysis of P2X7Rs on hiPSC-derived neurons. (a1-a5) Immunofluorescence analysis of hiPSC line 1-derived neurons stained with antibodies directed against epitope 576-595 of rat P2X7Rs (green) with double-labelling using neuronal marker β-III tubulin (red). (b1-b5) Immunofluorescence analysis of hiPSC line 2-derived neurons stained with antibodies directed against epitope AA 363 to 595 of mouse P2X7Rs (green) with double-labelling using the neuronal marker β-III tubulin (red).(c1-c5) Immunofluorescence analysis of hiPSC line 2-derived neurons stained with antibodies directed against epitope AA 576 to AA 595 (A1-A5) of rat P2X7Rs (green) with double-labelling using neuronal marker β-III tubulin (red). Scale bar 10 µM.
