a·liz·a·rin

(ă-liz'ă-rin), [C.I. 58000]
1,2-dihydroxyanthraquinone; a red dye that occurs in the root of madder (Rubia tinctorum and other Rubiaceae) in glucose combination (ruberythric acid) as orange needles, slightly soluble in water; used by the ancients as a dye. Now produced synthetically from anthracene and used in the manufacture of dyes, for example, alizarin blue, alizarin orange, Turkey red. As an indicator, it is yellow below pH 5.5 and red above pH 6.8; other modified alizarins have other colors and change color at other pH values.

Because the ATP-induced calcium mineral formation assay was mainly used to detect ATP-induced formation of CPPD crystals, we decided to further examine the FLSs-mediated calcium mineral formation and deposition in the absence of ATP using alizarin red, a method which can detect all types of calcium crystals.

Fig 3A-C shows the images of SPK samples excited for Alizarin red, tetracycline and calcein respectively; Fig3D shows superimposition image of A, B and C.
Here, we first examined the expression of miR-488 during osteoblast differentiation and found that it was two-fold higher in differentiated osteoblasts, as shown by alizarin red S staining, which is used to monitor calcium accumulation (i.e., mineralization) in the ECM (Figure 1(a)).
The specimen was then transferred in 1% KOH solution containing a few drops of 0.1 % alizarin red solution in water.
Furthermore, treatment of cells with EMD for 14 d caused a pronounced calcium accumulation in cell cultures, as determined by alizarin red S staining (Figures 3(b) and 3(c)).
