How Does Precipitating Aid in Staining Techniques?
Staining is a crucial step in histology used to highlight specific structures within tissue samples. Precipitating agents often react with specific cellular components to form colored precipitates, thereby enhancing contrast. For example, in the Feulgen reaction, acid hydrolysis of DNA results in the formation of aldehyde groups which then form a colored precipitate upon reaction with Schiff's reagent.
