Lugol's Hematoxylin

Stain Technology, 1983
A few years ago Clark et al. (1973) published a modification of Cole's hematoxylin (Cole 1943) which had several advantages. Not the least of these was the progressive nature of the stain and the use of stable stock solutions from which the stain could be prepared volumetrically. A distinct disadvantage was the necessity of preparing the stain 24 hours

Difficulties in Ferrous Iron Mordant Hematoxylin Staining and Some Hematoxylin Substitutes

Stain Technology, 1971
A gradual deterioration of intensity of sequence ferrous sulfate hematoxylin staining was traced, after elimination of hematoxylin quality as a cause, to a deterioration of the metal salt, associated with caking of the crystals. Fresh samples were also partly caked and ineffective.

Gomori's Hematoxylin as a cHromosome Stain

Stain Technology, 1953
The chromic hematoxylin of Gomori (1941) can be used as an excellent chromosome stain after hydrolysis of the tissue in warm 1–N hydrochloric acid. The hydrolysis must be accurately timed for different material as in the case of the Feulgen reaction. The staining of sections can be performed at room temperature and requires about 15 minutes.

The long history of hematoxylin

Biotechnic & Histochemistry, 2005
Hematoxylin is a naturally occurring chemical used as the basis of a dye in laboratories throughout the world to stain nuclei in microscope slide preparations. This chemical is extracted from the logwood tree Hematoxylon campechianum and was discovered by Spanish explorers to the Yucatan in 1502.

Mechanisms of chromation hematoxylin stains

Histochemie, 1969
In chromation hematoxylin sequence stains of Weigert-Smith-Dietrich type an exploration is presented of the nature of chromium binding tissue end groups, of the valency of the bound chromium and of the mechanisms and conditions of its binding.

Hematoxylin as a Pituitary Stain

Stain Technology, 1960
The accurate picture of the acidophil granules of the anterior pituitary which is provided by iron hematoxylin can be combined with the differential staining of the basophils by either the periodic acid-Schiff (PAS) or combined aldehyde-fuchsin-PAS procedures.
