Electrophoretic mobility shift assays of the footprinted CACCC site of the human ankyrin-1 gene promoter.
Gel mobility shift assays using oligonucleotides corresponding to the ankyrin-1 promoter footprinted CACCC site or a control β-globin CACCC site and nuclear extracts from COS cells transfected with a BKLF cDNA expression plasmid. BKLF antibody was added to the reaction mixtures where indicated.
