Longitudinal relaxation rates in parental, MagA- and HF + LF-expressing cells +/- iron supplementation.

Samplea	R1 (s–1)b	n
P	0.719, 0.821	2
P + Fe	0.762, 0.767	2
A	0.808 ± 0.025	5
A + Fe	0.812 ± 0.030	5
F	0.906 ± 0.053	3
F + Fe	0.794 ± 0.018	3

^aCells were incubated in the presence (+Fe) or absence of 250 μM ferric nitrate. P, parental; A, MagA expression; F, HF + LF expression.

^b Individual values are reported for n = 2. Mean + SEM is reported for n = 3–5.
