Figure Lengend Snippet: Location of vascular Cx across the vessel wall. A . Confocal images of triple (Cx, α-actin, CD31) immunohistochemical stainings of Cx40, Cx45, Cx37, and Cx43 in small resistance arteries. Left panel: Overlay of a z-series in xy-direction, right panel: Cross section (slice) of the z-stack in yz-direction along the yellow lines in the z-stack. The arrows depict the Cx expression in ECL (yellow) or beyond EC and within SMC (SMCL, white), scale bars: 10 μm. B . Summary of the Cx distribution within the ECL and SMCL for all Cx (n = 4-8, at least 3 vessels each; *: p < 0.001).
Article Snippet: After washing twice, and perfusing the for 5 min with PBS the vessels were incubated and perfused for 2 hours with PBS containing 1% BSA and 0.3% Triton-X100, washed and perfused again with PBS-1% BSA and incubated overnight with the antibodies against Cx37 (10 μg/ml Alpha Diagnostics, Cat. No. Cx37A11-A), Cx43 (see above), Cx40 (3.3 μg/ml polyclonal rabbit anti mouse-Cx40, Alpha-Diagnostics, Cat. No. Cx40-A) or Cx45 (2.5 μg/ml polyclonal rabbit anti Cx45 c-Term, Zymed, Cat. No. 40–7000) and against CD31 (2.5 μg/ml monoclonal rat anti mouse-CD31, Abcam, Cat. No 56299; antibodies were applied from the endothelial and smooth muscle side).
