Comparison of immunostaining with the GluR4-C and GluR4-N antibodies. Confocal images from lamina I stained with the GluR4-C, GluR4-N and GluR2 antibodies. A few puncta are labelled with the GluR4-C antibody (two marked with arrows). The GluR4-N antibody stains these strongly, but also labels several other puncta more weakly (two shown with arrowheads). All of the puncta labelled by each GluR4 antibody are GluR2-immunoreactive. Images were obtained from 4 optical spacing at 0.3 μm. Scale bar = 10 μm.
