WebbHematoxylin is a compound extracted from the heartwood of the logwood tree. Haematoxylin can be considered as a basic dye. It is used to stain acidic structures a purplish blue. DNA in the nucleus, and RNA in ribosomes and in the rough endoplasmic reticulum are both acidic, and so haemotoxylin binds to them and stains them purple. WebbHematoxylin can be ripened either by natural process by exposure to air and light and takes 3-4 months to ripen or by chemical oxidation using chemicals such as sodium iodate or mercuric oxide(16).By itself, hematoxylin is amphoteric in its hematein form; it is red at acid pH and blue at alkaline pH.
