Figure 1From: Immunogold electron microscopic evidence of in situ formation of homo- and heteromeric purinergic adenosine A1 and P2Y2 receptors in rat brainBar graphs comparing the relative distributions of A 1 R(A1)- and P2Y 2 R(Y2)-immunoreactive elements in each brain region (A-C) and in transfected HEK293T cells (D). The P2Y2R-P2Y2R, A1R-A1R and A1R-P2Y2R dimers are indicated by Y2-Y2, A1-A1 and A1-Y2, respectively. Total number of immunoreactive gold particles on the cell surface was defined as 100%. Each column represents the average frequency (± SD) from three cells. Raw data are shown in the tables under the graphs. Data are means of three independent experiments.Back to article page
