Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity/Sensitivity

Eosinophil peroxidase (F4O7J) Rabbit mAb recognizes endogenous levels of total Eosinophil peroxidase protein. This antibody recognizes the full-length precursor, heavy chain, and light chain subunits of human Eosinophil peroxidase protein. This antibody is not recommended for immunohistochemical analysis of mouse tissues.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asn585 of human Eosinophil peroxidase protein.

Background

Eosinophil peroxidase (EPX), also known as EPO, is a cationic protein stored in the secondary granulocytes of eosinophils (1-4). Unprocessed precursor EPX is an 80 kDa monomeric glycoprotein, which consists of two polypeptides linked by disulfide bonds: ~55 kDa heavy and ~15 kDa light chain (1-3, 6). In response to allergens or parasitic infection, eosinophils are recruited to affected tissues, where EPX catalyzes the formation of reactive oxidants lethal to tissue-invading parasites (1-4). In the tumor microenvironment of some breast cancers, eosinophils accumulate near blood vessels and infiltrate hypoxic regions, where EPX is released in high quantities by infiltrating immune cells (5). EPX may contribute to cancer progression by augmenting pro-tumorigenic collagen production and angiogenesis, making it a potential therapeutic target in breast cancer therapy (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
