Detection Principle Under the action of acidic solution and reductant, ferric ions can be separated from transferrin in serum, and reduced into ferrous ions (Fe2+). The latter then bind to bipyridine and form pink complexes. The concentration of iron can be calculated by measuring the OD value at 520 nm indirectly.
Synonyms Fe

The recommended dilution factor for different samples is as follows (for reference only):

Sample Type Dilution Factor
Human serum 1
Mouse serum 1
10% Mouse liver tissue homogenization 1
10% Rat kidney tissue homogenization 1

The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
