Description générale

Neutrophil Elastase (NE, EC 3.4.21.37, leukocyte elastase, ELANE, ELA2, elastase 2, neutrophil elaszym, or serine elastase) is a cytotoxic serine protease. It is stored in the azurophil granules of neutrophil granulocyte and is released following cell stimulation, e.g. by pathogens, immune complexes or chemotactic agents (PMA). Mutation in the gene ELA2 (neutrophil elastase) results in neutropenia, a hereditary disorder characterized by reduced neutrophil count in an individual.[1]

Application


  • Relationship between airway inflammation and airflow limitation in elderly asthmatics.: This study investigates the connection between airway inflammation and airflow limitation in elderly asthmatic patients. It highlights the role of neutrophil elastase in airway inflammation, which was measured using the Neutrophil Elastase Activity Assay Kit (Fluorometric). The findings suggest that targeting neutrophil elastase activity could help in managing airflow limitation in elderly asthmatics, offering potential therapeutic applications for the assay kit (Soma et al., 2020).

Adéquation

Suitable to determine the activity of purified Neutrophil Elastase, detect the activity of Neutrophil Elastase in plasma and/or blood and screen/study/characterize chemotactic agents causing Neutrophil stimulation and release of Elastase.

Principe

The Neutrophil Elastase Activity Assay Kit utilizes the ability of NE to proteolytically cleave a synthetic substrate and release a fluorophore, AFC, which can be easily quantified by fluorescence. This assay kit is simple, rapid, and can detect as low as 1 ng of neutrophil elastase in a variety of samples.

  1. will this kit work with human and mice sample both?

    1 answer
    1. This kit can be used to determine neutrophil elastase activity from both species. Please review the article citations below where researchers have reported this kit being used with neutrophils isolated from human blood and mice brain.

  2. Hi I am wondering if you have any references where this assay has been used with Human serum. Please let me know. Thanks.

    1 answer
    1. A detailed search of the scientific literature does not reveal any references to utilizing this kit with human serum. This kit has not been tested directly on serum samples. In theory, it could possibly work as long as the serum sample has active elastase. This may require some research and development to utilize the kit for the intended purpose. Please also keep in mind that the kit is used primarily for elastase from neutrophils which is a type of white blood cell. The serum should be devoid of white blood cells from the collection process.
