What is Alizarin Red S used for?
Alizarin Red S is used for the staining of cartilage and bone. It reacts with calcium, thereby helping in the diagnosis of calcium deposits. It is also used to study carbohydrate–boronic acid interactions.
Is Alizarin Red S an azo dye?
Alizarin red-S (ARS) is a type of azo dye that is widely used for dyeing of wool and nylon. It is toxic and carcinogenic and can cause a serious hazard to aquatic ecosystems.
Is Alizarin yellow soluble in water?

Is Alizarin Red Toxic?
Abstract. Alizarin red S (ARS) is a widespread mordant dye derived from alizarin. However, it was reported to be mutagenic and carcinogenic probably because it could induce oxidative damages in organisms. Catalase (CAT) is an important antioxidant enzyme defensing oxidative damages induced by xenobiotics.
What is Alizarin Red staining?
Alizarin red is a commonly used stain to identify calcium containing osteocytes in differentiated culture of both human and rodent mesenchymal stem cells (MSCs).
