    Abcam's Iron Assay Kit provides a simple convenient means of measuring Ferrous and/or Ferric ion in sample. In the assay, ferric carrier protein will dissociate ferric into solution in the presence of acid buffer. After reduction to the ferrous form (Fe2+), iron reacts with Ferene S to produce a stable colored complex and give absorbance at 593 nm. 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 20 nmol in 50 µl sample, or 8 µM to 400 µM iron concentration in various samples.

    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.

I contacted the laboratories. They confirmed that the assay buffer provided wtih ab83366 Iron Assay Kit has a pH of 4.6. Sulphuric acid is not known to interfere with the assay.


However, we would suggest to ensure that the pH level...

Though the assay is incompatible with chelating agents such as EDTA and citrate, it is compatible with heparin and should be effective for assays of plasma collected with heparin. We do not, however, have data that confirms this.

Unfortunately, this kit is not suitable for use with plasma samples due to the presence of iron binding transferrin in plasma leading to inaccurate measurements of free iron.

1. All components should be stored in aliquots according to individual use requirements at -20C to prevent freeze-thaw cycles.

2. The plate can be covered by a plate cover and aluminium foil to protect from light during incubation. The incubat...

Since the specific probe is proprietary they didn't have a spectrum to share, but in their experience reading at 570 nm should work and may simply reduce the sensitivity slightly.

Detection of iron levels in hair samples

Average Good 4/5 (Ease of Use)
Abreviews
We used the iron assay kit to evaluate whether iron can be detected in hair shaft samples. In this case, we used a hair sample from a Rhesus primate, since we had a sufficient amount to test. The hair sample was milled into a fine powder, homogenized with assay buffer (4x volume) and centrifuged as directed. We initially tested various small amounts of hair (ranging from 1.8 to 12.1mg), given that these samples are often only available in limited quantities. The resulting absorbance was very close to the base nm of the 0 standard, and translated to -0.043 to 0.034nmoles per 50μl sample. We had used two sets of standard concentrations: the set of standards recommended in the protocol (0-10nmol/well) and a 1:10 dilution of those standards (0-1nmol/well). Both standard curves had an R-value better than 0.98, and the diluted standard curve was used since it best encompassed the resulting nm.
We repeated the assay with a larger amount of hair (55.9mg). In the increased sample we were able to detect 0.14-0.23nmole per 50μl sample, which was closer to the stated range of the kit (0.4-20 nmole/50μl). This indicates that it is possible to detect iron in hair shaft sample using this kit. However, given the relatively large amount of sample needed, it is not an ideal method for limited sample sizes. The kit itself was very easy to use.

When the iron content in cell culture medium is <0.1uM, Transferrin is typically added to allow cell growth. Usually iron content is in the range of hundreds of micromolar in mammalian cell culture medium. We have never encountered such low iron con...

The buffer in this kit should be compatible with generic protein assays. We would prefer using the Bradford method. If the protein cannot be detected that way, we would recommend to have duplicates of the same number of cells. One of the samples can th...

This is a common problem seen in liver and serum samples. Lipoproteins in the sample are the main culprits behind this turbidity. For this purpose, we would recommend that to add 5 µl/well of 1 M SDS (28.8% or 288 mg/ml of SDS) to all thei...
