Ferritin ELISA Kit


Human ferritin ELISA kit is a reliable quantitative procedure for measuring ferritin in human serum and plasma (heparin, EDTA) samples. This assay has a minimum sensitivity limit of 0.04 ng/ml.


Ferritin is a water soluble, globular protein found in the liver and it is responsible for iron storage. The molecule is composed of an apoferritin shell which comprises heavy and light subunits that are surrounded by a crystalline core that is made up of phosphate and iron oxide. Apoferritin binds to free ferrous iron and then it stores this in a ferric state. Free iron is toxic to cells and the body has developed an elaborate set of protective mechanisms in order to bind iron in a number of different tissue compartments. Within the cells, iron can be found to be stored complexed to protein as either a ferritin or hemosiderin.

Ferritin is synthesized in; the liver, spleen and many other body tissues. The measurement of serum levels can be carried out routinely. It is a useful indicator for the early detection of iron deficiency (anemia) in apparently healthy people. It is also regarded as clinically significant when monitoring the iron status for renal dialysis patients, blood donors and pregnant women. Early methods that were used to detect iron levels were lacking in sensitivity and very invasive (causing unnecessary trauma to patients). The current procedure to determine levels in serum offer better sensitivity and are non-invasive (very little patient discomfort).


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
