Product Usage Information Western Blotting: 1:1000 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity FTH1 Antibody detects endogenous levels of total FTH1 protein. Nonspecific bands are seen above 80 kDa. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino-terminal region of FTH1. Antibodies are purified by protein A and peptide affinity chromatography. Background Ferritin is a ubiquitous and highly conserved protein that plays a major role in iron homeostasis by sequestering and storing iron in a non-toxic and bioavailable form (1). The assembled ferritin molecule, often referred to as a nanocage, can store up to 4,500 atoms of iron (2,3). It forms a holoenzyme of ~450 kDa, consisting of 24 subunits made up of two types of polypeptide chains: ferritin heavy chain (FTH) and ferritin light chain (FTL), each having unique functions. FTHs catalyze the first step in iron storage, the oxidation of Fe(II), whereas FTLs promote the nucleation of ferrihydrite, enabling storage of Fe(III) (4). In addition to iron buffering, FTH also enhances thymidine biosynthesis (5). Serum ferritin levels indicate the amount of iron stored in the body and is the most sensitive test for anemia. It is markedly elevated in inflammation, malignancy, and iron overload disorders (6). Research studies have found that defects in ferritin proteins are also associated with several neurodegenerative diseases (7).
