4′,6-Diamidino -2-phenylindole dihydrochloride is better known as "DAPI". It is a dry dye used for the preparation of a color staining solution that can be applied for fluorescence staining of DNA in nuclei in vivo or as counter stain in immunofluorescent methods in sample material of human origin. The dye is a CE certified IVD product and has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.
