Fig. 1From: The impact of neutrophil extracellular trap from patients with systemic lupus erythematosus on the viability, CD11b expression and oxidative burst of healthy neutrophilsThe detection of neutrophil-derived NET by immunofluorescence microscopy. To observe NET, activated (A photographs) PMNs or resting PMNs (B photographs) were fixed and immune-stained with specific anti-NE antibody followed by a fluorescent secondary antibody (red, middle photographs). The samples were stained with DAPI to counter stain the nucleus and extracellular DNA in blue (upper photographs). The overlay of the two channels is shown in the photographs at the bottom. All photos presented neutrophils from a control sample. NE: neutrophil elastaseBack to article page
