||in vitro, single molecule measurements. The 5' end of one strand of a 48.5 kilobase (kb)-long duplex lambda phage DNA molecule is attached to the bottom surface of a glass flow cell using a biotin–streptavidin linker. The opposite 3' end bears a digoxigenin moiety and is linked to a bead that is 2.8 microm in diameter and coated with anti-digoxigenin antibody
