What is the difference between using Harris
WebHematein is anionic, having a poor affinity for tissue, and is inadequate as a nuclear stain without the presence of a mordant. The most useful mordants for hematoxylin are salts of aluminum, iron, and tungsten, although hematoxylin solutions using lead as a mordant are occasionally used (for example in the demonstration of argyrophil cells). WebHarris hematoxylin is used on tissue sections to stain: a. fat b. glycogen c. nuclei d. cytoplasm b. oxidation *can be done naturally (atmospheric oxygen), or with oxidizing agents Ripening of hematoxylin is a process of: a. hydrolysis b. oxidation c. mordanting d. reduction a. hematein *hematoxylin is not a dye city of vancouver tax rates
