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.
