Stereoscopic FRIL images of neuronal vs. astrocyte gap junctions in developing rat spinal cord. (A) Small neuronal gap junction in P7 spinal cord labelled for Cx36 by three 5-nm gold beads but not labelled for Cx43 (10-nm and 20-nm gold; none present). (B) A medium-size astrocyte gap junction from P4 spinal cord labelled for Cx43 by eight 18 nm gold beads. This replica was also labelled for AQP4 (6 and 12nm gold beads). Arrow points to an E-face imprint of a square array, clearly marking this as an A/A gap junction. Calibration bars are 0.1 micron.
