  • 产品概述

    In Abcam's Neutrophil Elastase Inhibitor Screening Kit, NE hydrolyzes a specific fluorescent substrate to release the fluorescent group, which can be detected at Ex/Em = 400/505 nm. In presence of a potent Neutrophil Elastase inhibitor, the hydrolyzation of substrate will be inhibited or stopped. The kit provides a rapid, simple, sensitive, and reliable test suitable as a high throughput screening assay of Neutrophil Elastase inhibitors. For comparison of the relative efficacy of test inhibitors, a control inhibitor, SPCK (Ki = 10 µM for human leukocyte elastase) is included.

    Neutrophil Elastase (NE) is an aggressive and cytotoxic 29 kDa serine protease stored mainly in the azurophil granules of neutrophil granulocytes. It plays a role in the degradation of a wide range of extracellular matrix proteins, including fibronectin, laminin, proteoglycans, collagens, and elastin. When the extracellular NE concentration exceeds the buffering capacity of endogenous inhibitors, it becomes implicated in the signs, symptoms and disease progression of inflammatory lung disorders via its role in the inflammatory process, mucus overproduction and lung tissue damage.

RFU is an arbitrary unit and is dependent on the specific instrument and the gain/sensitivity, so unfortunately there is no way to give you a generic RFU to nmole correlation for calculation.

1. From what species is the elastase purified? Human.
2. What is the concentration of elastase provided? There is 15-22 mU of enzyme in the kit. The exact amount is proprietary.
3. What is the substrate? Eg. what is the sequence? MeOSuc - Ala -...

Yes. ab142178 is same as the substrate in ab118971.

Thank you for contacting us.

The substrate that is in the kit will be cleaved by active elastase, whether pure, as provided in the kit, or in biological samples. You could use the pure elastase in the kit as a standard for comparison to your...
