Ferritin Antigen >95%

Ferritin is a ubiquitously expressed iron-storage protein that sequesters and buffers intracellular free iron, and this purified antigen preparation from Antibodies.com functions as a standardized immunogen and calibration reference for iron-metabolism and acute-phase response research. Supplied as a liquid formulation at >95% purity in a 1 mg vial, the antigen supports reproducible signal generation in ELISA plate-based capture workflows and Western blot confirmation experiments where a defined positive control or calibrator is required. Investigators studying anemia of chronic disease, hemochromatosis, inflammation-associated hyperferritinemia, and hepatic or neurodegenerative iron-overload models use this reagent to spike sample matrices, validate antibody-pair performance, and confirm band identity on transferred blots. The >95% purity threshold reduces background from contaminating host-cell or non-target proteins that would otherwise compete for antibody binding on coated microplate wells or generate extraneous bands during SDS-PAGE separation, both of which directly affect quantitative readout accuracy. Researchers are advised to confirm lot-specific handling on the accompanying datasheet before first use, since the liquid format generally calls for aliquoting on receipt to limit repeated freeze-thaw exposure of the working stock.
