Ferritin is important in iron homeostasis. It is the main iron-storage protein, composed of two partially homologous subunits, heavy and light chains. Ferritin molecules in cells containing high levels of iron tend to be rich in light chains, and may have a long-term storage function, whereas heavy-rich ferritins are more active in iron metabolism. Mutations in the ferritin gene cause the hereditary hyperferritinemia-cataract syndrome and neuroferritinopathy, associated with inflammation. Elevated levels of ferritin are reported as characteristic of adult-onset Still's disease and hemophagocytic syndrome, also associated with inflammation. Microfilaments and increased levels of exogenous ferritin are excreted directly into the bile by way of a second microfilament-independent, chloroquine-insensitive pathway, supporting a possible physiological mechanism for the release of ferritin from the liver.
Applications:
Suitable for use in ELISA. Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Affinity Constant:
4x10e10 L/mole
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
