Table 4.

Trace element analysis of cells cultured in the presence or absence of iron supplementation*.

Sample Iron# Zinc# Fe/Zn n
A 0.047 ± 0.006 0.249 ± 0.047 0.19 7
A + Fe 0.667 ± 0.111 0.117 ± 0.008° 5.70 7
F 0.044 ± 0.008 0.183 ± 0.034 0.24 5
F + Fe 0.650 ± 0.113 0.139 ± 0.015° 4.68 4

Data were collected using either ICP–AES or –MS.

*

Cells were incubated in the presence (+Fe) or absence of 250 μM ferric nitrate.

#

Elemental analysis is reported as μg/mg protein; mean ± SEM.

Samples +/- Fe were evaluated using the Student’s t-test and showed significance at p < 0.01.

°

Samples +/- Fe were evaluated using the Student’s t-test and were not significant: p > 0.01.
