Expression of Kv1.3 in HEK 293 cells and OBNs. Photomicrographs of Kv1.3-transfected HEK 293 cells (A, B) and OBNs (C, D), under bright-field illumination (A, C) and epifluorescence (B, D). Cells were immunolabeled with an antibody directed against a putative extracellular domain in Kv1.3 and visualized with a fluorescent-conjugated secondary antibody.
