Descrizione

Descrizione generale

Neutral red (C.I. 50040) - for microscopy Certistain^®, is a dry staining dye that is used to prepare a staining solution, that makes target structures in hematological specimen materials evaluable for diagnostic purposes. Neutral red belongs to the group of azines. Neutral red can be used for several staining such as supravital staining of leukocytes .In histology for nuclear staining, fluorescence staining, polychrome staining or for counterstaining in Gram staining. As CERTISTAIN^® dye it is chemically quality-certified according to highest standards and strict specifications.
