After fusing your protein of interest to one to the dimerization tags provided with iDimerize Homodimerization Systems (DmrB) or iDimerize Heterodimerization Systems (DmrA and DmrC), you may wish to monitor the protein"s expression by SDS-PAGE followed by Western blot. These sensitive antibodies give a clean band on a Western blot. The DmrA and DmrB antibodies are monoclonal mouse antibodies, and the anti-DmrC antibody is polyclonal, derived from rabbit.
