Robust Neutrophil Extracellular Trap Assay Kit

Robust Neutrophil Extracellular Trap Assay Kit

Cambridge Bioscience offers an easy-to-use assay for the accurate quantification of extracellular NET-associated elastase activity. Unlike nucleic acid stains which can suffer from false positives due to DNA release from necrosis, this protocol includes a step to wash away non-NET associated elastase following NET generation. This offers a DNA-independent readout of NET generation by measuring absorbance of the specific cleaved elastase substrate (N-methoxysuccinyl-Ala-Ala-Pro-Val p-Nitroanilide) at 405nm. Both PMA and calcium ionophore A-23187 are included as stimuli for inducing NET generation.

Benefits Of Using This NET Assay Kit
• Non-dsDNA readout eliminating false positives from DNA release by necrosis
• Quantifiable results
• Strong signal
• Easy to follow protocol
• Elastase-based analysis
• Adaptable to multiple species by using enzymatic activity rather than NET component antibodies
