Hematoxylin (Delafield's)is used as staining solution for Blood films for spirochaetes, Protozoa and other purpose.This schedule allows each stain to be individually, and independently, controlled at the will of the operator. Delafield's hematoxylin is one of the most useful histological stains for the precise staining of cellulose cell waIls.
Use of expired hematoxylin impacts staining intensity, i.e., hematoxylin staining intensity decreased as the age of the expired reagents increased.

Hematoxylin and eosin (H&E) is the most widely used stain in histology and allows localization of nuclei and extracellular proteins. Hematoxylin, not a dye itself, produces the blue Hematin via an oxidation reaction with nuclear histones causing nuclei to show blue.
