When blood films are stained using Giemsa Stain, the nucleus and cytoplasm of white blood cells take on characteristic blue or pink coloration. The use of purified eosin and thiazine dyes minimizes lot-to-lot variation.

Supplier: SIGMA ALDRICH MICROSCOPY

Certified for Giemsa stain for blood films and for the Wolbach′s Giemsa method for paraffin sections. Giemsa is a versatile polychromatic stain, which is suitable for staining a diverse range of specimens. It is a buffered thiazine-eosinate solution designed to provide coloration of blood cells. Giemsa’s stain is frequently used for diagnostic purposes in hematology to differentiate the nuclear and cytoplasmic morphology of platelets, RBCs, WBCs, and parasites. It is frequently used in combination with other dye solutions as May-Grunwald’s solution for Pappenheim (MGG) and Wright-Giemsa. The Giemsa stain was adapted to histology due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. Giemsa′s staining solution is composed of methylene blue, azure, and eosin.

Supplier: SIGMA ALDRICH MICROSCOPY

1-Methoxy-5-methylphenazinium methyl sulfate (MPMS) is a photochemically stable electron-transport mediator between NAD(P)H and tetrazolium dyes. The reduced form of MPMS converts tetrazolium salt to purple precipitate formazan. It is a very stable and non-enzymic electron carrier that mediates electron transfer by dehydrogenases in vitro to various electron acceptors such as tetrazolium dyes or the electrode of an enzymic electric cell.
