abstract：:A protein-DNA complex has less gel electrophoretic mobility than the free DNA fragment. One parameter for the degree of retardation of a linear DNA fragment in a protein-DNA complex is the molecular weight of the bound protein(s). The quotient of the migration distances of free DNA (m) and protein-DNA complex (m') is ...
