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.

For a carrier free (BSA and azide free) version of this product see product #18923.

Specificity / Sensitivity

Neutrophil Elastase (E8U3X) Rabbit mAb recognizes endogenous levels of total neutrophil elastase protein. This antibody does not cross-react with human neutrophil elastase protein. Non-specific staining was observed in the vas deferens by immunohistochemistry.

Species Reactivity:

Mouse

Source / Purification

Monoclonal antibody is produced by immunizing animals with full-length recombinant protein specific to mouse neutrophil elastase protein.

Background

Neutrophil elastase is a hematopoietic serine protease that belongs to the chymotrypsin superfamily and plays a critical role in the innate immune function of mature neutrophils and monocytes (1,2). Neutrophil elastase is actively synthesized as an inactive zymogen in myelocytic precursor cells of the bone marrow, which then undergoes activation by limited proteolysis and sorting to primary (azurophil) storage granules of mature neutrophil granulocytes for regulated release (3,4). Research studies have shown that neutrophils play a significant role in mediating the inflammatory response through the release of neutrophil elastase, which activates pro-inflammatory cytokines and degrades components of the extracellular matrix and Gram-negative bacteria (5). Mutations in the gene encoding neutrophil elastase, ELA2, have been implicated in hematological diseases such as cyclic and severe congenital neutropenia, which is characterized by defects in promyelocyte maturation (6,7).
