How do eosinophils respond to staining?

Eosinophils are a type of white blood cell that is part of the immune system, primarily involved in combating parasitic infections and playing a role in allergic reactions. When it comes to their staining properties, eosinophils have distinct granules in their cytoplasm that contain proteins which are rich in acidic components, specifically eosinophil peroxidase.

These granules readily take up acidic dyes, such as eosin, which is why eosinophils are known to stain well with acidic dyes. This staining behavior allows for easy visualization of eosinophils under a microscope, typically giving them a bright pink or orange appearance due to the eosin dye. This characteristic staining property is a key feature in identifying eosinophils in blood smears or tissue sections.

In summary, eosinophils respond to staining by being highly receptive to acidic dyes, leading to the conclusion that they stain with these types of dyes, which is why the choice stating they stain with acidic dyes is correct.
