What is unique about neutrophils in terms of staining?

Neutrophils are unique in that they can be stained equally well by both acidic and basic dyes, which is why they fall under the category of cells that stain with neutral dyes. This characteristic is largely due to the presence of granules within neutrophils that contain proteins, enzymes, and other substances that can react with both types of dyes. The granules are generally neutral in charge, allowing them to take up both types of stains, making it easier to visualize neutrophils under the microscope in histological studies. This property is helpful in differentiating neutrophils from other types of white blood cells that may preferentially take up either acidic or basic stains. Consequently, the ability to be stained with both types of dyes allows for more versatile examination of these important immune cells in various lab contexts.
