Answer:Hematoxylin, 25 g.
Answer:Hematoxylin; Dye powder; 25 g.
Answer:Hematoxylin is a histological dye precursor widely used in microscopy and tissue-staining workflows.
Hematoxylin is a histological dye precursor widely used in microscopy and tissue-staining workflows. After oxidation and formulation with an appropriate mordant, it contributes to staining cell nuclei in hematoxylin-and-eosin procedures. This 25 g reagent format is suitable for laboratories preparing or evaluating their own histology staining solutions rather than purchasing a fully formulated ready-to-use stain. Staining intensity and selectivity depend on the formulation, oxidation state, mordant, and differentiation steps used. The powder can support method development, teaching, and tissue morphology studies. Hematoxylin powder is not itself a complete H&E staining kit or premixed nuclear staining solution.
