An azurophil is an object readily stained with an azure dye. [1] Azurophils include certain cytoplasmic granules[2] in white blood cells and hyperchromatin, imparting a burgundy or merlot coloration. Neutrophils in particular are known for containing azurophils loaded with a wide variety of anti-microbial defensins that fuse with phagocytic vacuoles. Azurophils may contain myeloperoxidase, phospholipase A2, Acid Hydrolases, Elastase, defensins, neutral serine proteases, bactericidal/permeability-increasing protein, [3] lysozyme, cathepsin G, proteinase 3, and proteoglycans.
Azurophil granules are also known as "primary granules".[4]
