Table 5.

Channel sizes of regimes of confinement for DNA in a high ionic strength buffer. The values in this table are based on 5 × TBE buffer (165 mM), with the persistence length l_p = 50nm and an effective width w = 4.7nm.⁹² For λ DNA, the radius of gyration is R_g = 0.73 μm.⁶²

Regime	〈X/L〉	Channel Size
Bulk	L^−2/5	D > R_g
de Gennes	D^−0.701	530nm < D < R_g
Extended de Gennes	D^−0.701	100nm < D < 530nm
Transition	D⁻¹	50nm < D < 100nm
Odijk	Eq. (50)	D < 50nm
