Oil Red-O is a fat-soluble azo dye belonging to the Sudan dye family.  It is widely used for fat staining   because of its obvious color development and easy observation.

Under the effect of adipogenic differentiation, mesenchymal stem cells (MSCs) are induced to differentiate into preadipocytes and adipocytes, and the latter gathers large and small fat droplets.  The solubility of Oil  Red O in fat is greater than that in dye solution, which makes the fat color red or orange.

Manufactured under ISO 13485 QMS and in compliance with applicable cGMP guidelines.
