Binding Assay: DNA binding assays using recombinant MBDs. To produce recombinant His6-tagged MBD polypeptides from human MBD2 (MBD2-MBD), MBD2-MBD cDNA was amplified from clone MGC-45084 (American Type Culture Collection), using PCR primers containing BamHI and EcoRI recognition sites (5'-GGATCCATGGAGAGCGGGAAGAGGATGGA-3' (SEQ ID NO:1) and 5'-GAATTCCATCTTTCCAGTTCTGAAGT-3' (SEQ ID NO:2)), and then introduced into pFBC6H, a modified pFastBac-1 baculovirus expression vector (Invitrogen), that had been linearized via cutting with EcoRI and XbaI. This pFB6H-MBD2 expression construct was used to transform DH10BacE. coli competent cells (Invitrogen) to form an MBD2 expression bacmid via site-specific transposition. The MBD2 expression bacmid was then transfected into Sf9 insect cells for production of recombinant MBD2 baculovirus particles, which were used to infect Sf9 cells (1 MOI, 48 hours) to generate recombinant MBD2 protein.
