Iron Assay kit LS – Ferrozine method | Metallo Assay LS

Date：June 11 2020Web Page No：80480

Metallo Assay Iron Assay Kit LS (Ferrozine Method) can measure Iron ion (Fe²⁺/Fe³⁺ ) in the biological samples such as Plasma, Serum, Urine, and wide range of samples by microplate reader.

Iron is contained in various enzymes as an important constituent element. Iron in the blood are all combined to transferrin, and transported to erythroblast and tissues for synthesis of globin proteins such as myoglobin and hemoglobin which requests iron. Iron is essential for generation of oxigen transporting proteins. Deficient of such proteins cause hypoferric anemia, chronic bleeding anemia, and infectious anemia. Increase of transferrin and high concentration of iron are reported in hepatitis and liver cirrhosis. Increase of iron is reported in Hypoplastic anemia and malignant anemia.

Features

Using microplate reader for assay, no need to use Atomic Absorption Spectrometry or ICP-OES Optical Emission Spectrometry, which have been mainly used so far.
Good correlation with the result of Atomic Absorption Spectrometry and ICP-OES.
High throughput measurement by using microplate reader.
All animal species sample can be measured.
Assay time : just 10 minutes!
1 point calibration – do not need multiple point measurement to make standard curve (r²=0.9999).
Kit does not contain any hazardous components like cyanide or azide as preservative.
Samples : Serum, Plasma, Urine, Saliva, Cell lysate, Tissue extract, Hair extract, Water, etc.
In combination with UIBC Assay kit LS Bathophenanthroline method (#UIB02AE), TIBC (Total Iron Binding Capacity) can be measured.

Assay Principle

This kit measures iron concentration by color change caused by chelate complex formulation of Ferrozine and Iron. Iron combined to transportation protein such as transferrin is denatured by weak acid and denaturant then formulates Iron-Ferrozine chelate complex. Measuring this complex by 560 nm wavelength and obtain iron concentration.

Sample Preparation

Samples which do not require preparation : e.g. Serum, Plasma and Urine
* EDTA treated sample is not suitable for this assay.
* Pooled urine should add HCl for storing. When assay, adujust sample pH 2 to 3.

Samples which require acid extraction : e.g. Cell Lysate, Tissue Homogenate and Other liquid samples
* Measurable chemical species is limited as follows:
　　・Free iron
　　・Iron binds to protein (Protein-Fe2+, e.g. albumin, metallothionein)
* Lysis buffer contains EDTA is not suitable for this assay.
* Organoiron and Heme iron requires acidolysis.

Microwave method and samples require acidolysis : e.g. Samples contain strong chelate agents such as EDTA, Organoiron (in the case of single bond -C-Fe-C-), Iron in cyclic ligand (Fe-Porphyrin)
* After acidolysis, adjust sample pH in 2 to 3.

Handling Procedure

(1)Apply DW, Standard and Sample (40 uL) to 96 well plate.
(2)Add R-A buffer (200 uL).
(3)Incubate at room temperature for 5 minutes.
(4)Read the absorbance at 560 nm (main) as OD1.
(5)Add R-R Chelate Color (8 uL).
(6)Incubate at room temperature for 5 minutes.
(7)Read the absorbance at 560 nm (main) as OD2.
(8)Calculate concentration. ΔODStd = (OD2Std - OD1Std) - (OD2Bl1 - ODBl) ΔODS = (OD2S - OD1S) - (OD2Bl - OD1Bl) Iron (ug/dL) = ΔODS/ΔODStd x 200 Iron (uM) = ΔODS/ΔODStd x 35.8	*ODS : OD sample, ODBl : OD blank, ODStd : OD Standard
