Fixation and dye (固定・染色)


Tracer (トレーサー)

substances making easy to trace the target substances, etc.
Methylene blue (メチレンブルー)
MB IUPAC name = 3,7-bis(dimethylamino)- 5-phenothiazinium chloride
stainin nucleus
insoluble in diethyl ether, soluble in water, alcohol such as ethanol, and chloroform
redox indicator (酸化還元指示薬)
Giemsa stain =
mixture of methylene blue and eosin ← staining red blood cell, platelet, etc.




Trypan blue (トリパンブルー)
MB
diazo dye ← a vital stain used to selectively color dead tissues or cells blue
Evans blue (エバンスブルー)
