Fig. 2. Western blot analyses of Cx43 and Cx31 in heart and brain lysates. Lane 1: Cx43^+/+; lane 2: Cx43^+/31; lane 3: Cx43^31/31. Cx43 protein was not detected in Cx43^31/31 animals (lane 3). Cx31 was not found in the Cx43^+/+ heart and brain (lane 1), whereas it was expressed in Cx43^+/31 mice and there was nearly double the amount in Cx43^31/31 animals (lane 2 and lane 3). Loading of equal amounts of homogenates was verified by re-immunostaining with monoclonal anti-tubulin.
