Which statement about Eosin Y is accurate? A) It highlights cytoplasmic granules without any clarity. B) It binds to basic groups like hemoglobin. C) It is a basic dye that stains nuclear chromatin. D) It is ineffective in staining basophil granules.
Understand the Problem
The question is asking for the accurate statement regarding Eosin Y, which is a dye commonly used in histology. We need to evaluate the provided options to identify which one correctly describes the properties and uses of Eosin Y.
Answer
It binds to basic groups like hemoglobin.
The final answer is B) It binds to basic groups like hemoglobin.
Answer for screen readers
The final answer is B) It binds to basic groups like hemoglobin.
More Information
Eosin Y is an acidic dye that binds to and stains cytoplasmic proteins pink because these proteins are typically basic, aligning with the function of eosin to bind with basic or positively charged groups, such as found in hemoglobin.
Tips
Confusing acidic dyes with basic dyes and vice versa. It's important to remember that acidic dyes like eosin stain basic components.
