Hepcidin, 25aa (Hepc, LEAP, Hepatic Bactericidal Protein, Liver Expressed Antimicrobial Peptide)

Hepcidin (Hepc, hepatic bactericidal protein) or LEAP (liver expressed antimicrobial peptide) is small, cysteine-rich peptide, antimicrobial peptide similar to defensins and thionins. Hepcidin (unprocessed, proprotein in mouse 83aa, rat/human 84aa) are almost exclusively produced in liver. Human hepcidin is produced from 84aa precursor, including a putative 24aa signal peptide. The secreted form of hepcidin in blood and urine consists of C-terminal 20, 22 or 25aa residues. The link between hepcidins and iron metabolism is that hepcidin expression is abolished in mice exhibiting iron-overload due to the targeted disruption of USF2 (upstream stimulatory factor 2) gene resembling the situation in hfe-/- mice. The human gene is located at chromosome 19, in close proximity with Usf2 gene. Hepcidin levels are increased in iron loading and in beta-2 microglobulin knockout mice. Hepcidins are devoid of IRE. Like other antimicrobial peptides, hepcidin is upregulated by lipopolysaccharides (LPS).\n\nApplications: \nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000-1:5000 (ECL).\nELISA: 1:100,000 using 50-100ng control peptide/well.\nOptimal dilutions to be determined by the researcher.\n\nControl Peptide: \nH2008-52: Hepcidin, 25aa, Human, Control Peptide \n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage, 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.

Additional Info

Recognizes all 3 processed forms of human HEPC. The human sequence is conserved in all 3 human HEPC peptides (20-, 22- and 25-aa C-terminal fragments). May react with the unprocessed larger 60aa pro-HEPC if present in the samples or tissues. Species Sequence Homology: mouse: 69%, rat: 61%.
