一般描述
Methylene blue (C.I. 52015) for microscopy Certistain® is a dry dye that is used in bacteriology for an overview stain and as counterstaining for Ziehl-Neelsen method in sample material of human origin. Bacteria appear blue. The dye has a further important application in hematology: Methylene blue and eosin are the main components of many staining solutions and dye mixtures. Certistain® is the product group for seleceted high quality dyes that fulfill all quality requirements of IVD and CE registration. For more details, please see instructions for use (IFU).
