Fig. 4From: Angiopoietin 1 release from human neutrophils is independent from neutrophil extracellular traps (NETs)Ang1 is released independently from NETs. Neutrophils from HC subjects were stimulated with PBS, LPS (100 nM), PMA (25 nM), or A23187 (5 μM) for 3 h to induce NETosis. Following stimulation, neutrophils were incubated with a primary unconjugated Ab (Rabbit α-human Ang1), followed by an incubation with a conjugated secondary Ab (Alexa Fluor 488 goat anti-rabbit; white). For the negative control, neutrophils were incubated only with the secondary Ab (blue boxes). Neutrophils were labeled with wheat germ agglutinin (conjugated with Alexa 647; red) and NETs were labeled with SYTOX Orange (green pseudo-color). Maximum intensity projection from acquired Z-stack were obtained by confocal microscopy (LSM 710, Carl Zeiss) using a Plan Apochromat 40x/1.3 oil DIC objectiveBack to article page
