Verification of deletion of the MR from BMDCs. Western blot for the MR using an antibody raised to the MR N terminus. A band was detected in the wild type sample of the correct size for MR (Lanes 1 and 2) and substantially reduced expression in the Cre recombinase expressing mice (Lanes 3 and 4). Purified MR from mouse kidney (Lane 5) served as control.
