Preparing Stock Solutions

Biological Activity

Description	Hematoxylin (Hydroxybrazilin) is a compound that forms strongly colored complexes with certain metal ions, notably Fe(III) and Al(III) salts and a kind of stain in histology.
In vitro	1. Place the glass slides that hold the paraffin sections in staining racks. Clear the paraffin from the samples in three changes of xylene for 2 min per change. 2. Hydrate the samples as follows. i. Transfer the slides through three changes of 100% ethanol for 2 min per change. ii. Transfer to 95% ethanol for 2 min. iii. Transfer to 70% ethanol for 2 min. iv. Rinse the slides in running tap water at room temperature for at least 2 min. 3. Stain the samples in Hematoxylin solution for 3 min. 4. Place the slides under running tap water at room temperature for at least 5 min. 5. Stain the samples in working eosin Y solution for 2 min. 6. Dehydrate the samples as follows. i. Dip the slides in 95% ethanol about 20 times. ii. Transfer to 95% ethanol for 2 min. iii. Transfer through two changes of 100% ethanol for 2 min per change. 7. Clear the samples in three changes of xylene for 2 min per change. 8. Place a drop of Permount over the tissue on each slide and add a coverslip. View the slides using a microscope.
