Description

Celestine Blue CAS NO 1562-90-9 is a synthetic cationic dye belonging to the oxazine class, widely recognized for its role as a nuclear stain in biological and histological applications. Its primary value lies in its ability to form stable complexes with specific tissue components, providing excellent contrast and definition in microscopic analysis. This product is essential for research laboratories, diagnostic facilities, and industrial quality control units involved in material science and life sciences.

Application

• Histological Staining: Used as a nuclear counterstain in conjunction with other dyes, such as in the Celestine Blue-Bismarck Brown Y sequence for connective tissue.
• Cytological Analysis: Employed for staining cell nuclei in smears and tissue sections, providing clear visualization of nuclear morphology.
• Textile Dyeing: Functions as a colorant for protein-based fibers like wool and silk in specialized textile applications.
• Ink Manufacturing: Serves as a pigment component in the formulation of specialized inks, including those for security printing.
• Biological Research: Utilized as a fluorescent probe or a component in complex staining protocols for research in cell biology and pathology.
• Material Science: Applied in the development of light-sensitive materials and as an indicator in certain chemical processes.
