| Method |
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 |
| Comments |
The rate of leading-strand synthesis (164±20 bps^-1, n = 13) is identical to that measured in ensemble experiments [ref 22], confirming that the force exerted on the DNA has no influence on the enzymatic activities. |
