Principle of the Assay: FE ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-FE antibody and an FE-HRP conjugate. The assay sample and buffer are incubated together with FE-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the FE concentration since FE from samples and FE-HRP conjugate compete for the anti-FE antibody binding site. Since the number of sites is limited, as more sites are occupied by FE from the sample, fewer sites are left to bind FE-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The FE concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes the heavy subunit of ferritin, the major intracellular iron storage protein in prokaryotes and eukaryotes. It is composed of 24 subunits of the heavy and light ferritin chains. Variation in ferritin subunit composition may affect the rates of iron uptake and release in different tissues. A major function of ferritin is the storage of iron in a soluble and nontoxic state. Defects in ferritin proteins are associated with several neurodegenerative diseases. This gene has multiple pseudogenes. Several alternatively spliced transcript variants have been observed, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]
Uniprot Description
Ferritin-H: Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney. Oligomer of 24 subunits. There are two types of subunits: L (light) chain and H (heavy) chain. The major chain can be light or heavy, depending on the species and tissue type. The functional molecule forms a roughly spherical shell with a diameter of 12 nm and contains a central cavity into which the insoluble mineral iron core is deposited. Belongs to the ferritin family.

Product Notes
The Rabbit FE fth1 (Catalog #AAA722529) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA722529 ELISA Kit recognizes Rabbit FE. It is sometimes possible for the material contained within the vial of "Ferritin, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
