What defines the eosinophilic nature of a cell's cytoplasm when stained?
Understand the Problem
The question is asking about the characteristics that define the eosinophilic nature of a cell's cytoplasm when it is stained, specifically looking for an explanation or identification of relevant cellular components that contribute to this property.
Answer
Eosinophilic nature is due to affinity for acidic dye eosin, staining basic structures pink.
The eosinophilic nature of a cell's cytoplasm is defined by its affinity for the acidic dye eosin, which stains it red or pink. This occurs because the cytoplasmic structures that are basic or acidophilic attract the negatively charged eosin molecules.
Answer for screen readers
The eosinophilic nature of a cell's cytoplasm is defined by its affinity for the acidic dye eosin, which stains it red or pink. This occurs because the cytoplasmic structures that are basic or acidophilic attract the negatively charged eosin molecules.
More Information
Eosinophilic staining is commonly used in histology, especially with hematoxylin and eosin (H&E) stains. The specific coloration helps in differentiating cell structures for analysis under a microscope.
Tips
A common mistake is confusing eosin (an acidic dye) with basic dyes, which instead stain acidic structures.
