Product overview
Iron Assay Kit ab83366 provides a simple convenient means of measuring ferrous (Fe2+) and/or ferric (Fe3+) iron in biological samples.
In the iron assay protocol, ferrous iron (Fe2+) reacts with Ferene S to produce a stable colored complex with absorbance at 593 nm. Ferric iron (Fe3+) can be reduced to form Fe2+ enabling the measurement of total iron (Fe2+ and Fe3+). The level of ferric iron (Fe3+) is calculated by subtracting ferrous iron from total iron.
A specific chelate chemical is included in the buffer to block copper ion (Cu2+) interference.
The kit measures iron in the linear range of 0.4 to 10 nmol or 8 µM to 200 µM.Iron assay protocol summary:
- add samples and standards to wells
- for Fe2+ assay add assay buffer only, for total iron (Fe2+ and Fe3+) add iron reducer
- incubate for 30 min at 37ºC
- add iron probe and incubate for 60 min at 37ºC
- analyze with microplate readerChinese protocol available. See protocols section below.

Relevance
Iron is essential to nearly all known organisms. It is generally stored in the centre of metalloproteins, in the heme complex, and in oxygen carrier proteins. Inorganic iron also contributes to redox reactions in the iron-sulfur clusters of many enzymes, such as nitrogenase and hydrogenase. -

Leal SM Jr et al examined if iron availability regulates fungal growth in an infection as fungal infection intiates an iron sequestration response. Mice given Fe-dextran (Fe-Dex) and deferoxamine (Defox) shows a higher fungal mass (Fungal dsRed) compared to vehicle treated mice over 48 hours. Iron content was quantified in mouse serum using Iron assay kit (ab83366).
