Unidirectional uptake rates, K_in, of free and Tf-bound iron for choroid plexus and cerebrospinal fluid (CSF)

Samples	K_in (μL/min/g)
Samples	⁵⁹Fe-only	⁵⁹Fe-Tf
Choroid plexus	10.39 ± 2.00^b	13.15 ± 2.50^*^b
CSF	0.17 ± 0.01	0.09 ± 0.02^a

Values are mean ± SEM, n = 3–5.

^*

Not significant for choroid plexus ⁵⁹Fe-Tf versus ⁵⁹Fe-only.

^a

p < 0.05, for CSF ⁵⁹Fe-Tf versus ⁵⁹Fe-only.

^b

P < 0.001 for choroid plexus versus CSF.
