瑞氏染色液 [瑞氏色素, 瑞士染料]，Wright stain；suitable for blood stain

Wright′s stain solution is commercially available and is generally used in hematology. The procedure of making it includes heating methylene blue with sodium bicarbonate, followed by combining the mixture with eosin. It is an alkaline solution; hence its concentration is continuously changing, owing to the progressive oxidizing action of the alkali, therefore Giemsa′s stain is added to preserve the azurophilic properties of the polychrome dyes.

 

Wright stain can be used for

• staining of chromosomes
• the exudate analysis of white blood cell concentration
