Product Description:
Once used as a food colouring but now banned throughout the EC Cudbear is a dye extracted from orchil lichens that produces colour's in the purple range. It can be used to dye wool and silk, without the use of mordant. Cudbear was the first dye to be invented in modern times, and one of the few dyes to be credited to a named individual. Orcinol is extracted from archil lichen, Rocella tinctoria. It is then converted to orcein by ammonia and air. Orcein is a reddish-brown dye, orchil is a purple-blue dye. aminoorceinimines.

Product Description:
Giemsa Stain is a laboratory reagent and stain for microscopy. A compound of eosin with methylene blue and its oxidation products. When blood films are stained using Giemsa stain, the nucleus and cytoplasm of white blood cells take on a characteristic blue or pink coloration. Giemsa stain functions by rearranging chromatin and inducing G bands producing a high quality stain for chromatin and the nuclear membrane. Giemsa stain is used to differentiate nuclear and/or cytoplasmic morphology of platelets, RBCs, WBCs, and parasites (1,2). The most dependable stain for blood parasites, particularly in thick films, is Giemsa stain containing azure B. Liquid stock is available commercially. The stain must be diluted for use with water buffered to pH 6.8 or 7.0 to 7.2, depending on the specific technique used.

Product Description:
Leishman's stain is applied in conventional staining techniques to uniformly stain chromosomes. These techniques leave centromers constricted, thus enabling the measurement of chromosome length, centromeric position, and arm ratio. Slides can be easily destained and banded by most banding procedures.
