Effect of A-tract phasing on the mobility differences observed in TBA⁺ and Li⁺

	TBA+			Li+
A-tract	Δμ(in)	Δμ(out)	ΔΔμ	−Δμ(in)	−Δμ(out)	ΔΔμ
A5=T5(2)	0.0151	0.0154	0.0003	0. 0124	0.0107	0.0017
A5(2)	0.0183	0.0220	0.0037	0.0109	0.0098	0.0011
A3T3(4)	0.0236	0.0262	0.0028	0.0088	0.0078	0.0010
A4T4(0)	0.0402	0.0401	0.0001	0.0138	0.0114	0.0024
Mean			0.0017			0.0016
SD			0.0015			0.0006

The mobility differences, in m.u., observed for each phasing pair, Δμ(in) and Δμ(out), and the absolute value of the difference in the mobility differences, ΔΔμ = $\left|\Delta \mu \left(\text{in}\right)-\Delta \mu \left(\text{out}\right)\right|$, are indicated. For brevity, the oligomers are identified only by their A-tracts and the number of flanking A·T basepairs; the phasing is given in the column headings.
