linking number differences ΔLk between relaxed plasmid states (Lk₀) and the plasmids in closed form (Lk), for the two supercoiling states and for the two deposition conditions.

$\mathrm{\Delta }Lk=Lk-L{k}_0$	−SC0	+SC300
APTMS (pure B-DNA)	274–286 = −12	297–286 = +11
MgCl2 (hybrid form)	274–281 = −7	297–281 = +16
