Contact | Scientific Protocols is part of the Reproducibility Initiative | How- These timings and densities of course depend on the cell type and concentrations of your differentiation components. I plan on preparing fresh Alizarin Red S by adding the powder to 100ml of distilled water. Saxe, D and Priest, JH (2010) General cell culture principles and fibroblast culture, Chapter 4. The reaction is not strictly specific for calcium, since magnesium, manganese, barium, strontium, and iron may interfere, but these elements usually do not occur in sufficient concentration to interfere with the staining. Dmitry Ovchinnikov; Cold Spring Harb Protoc; 2009; doi: 10.1101/pdb.prot5170 . Alizarin Red, an anthraquinone derivative, may be used to identify calcium in tissue sections and cultured cells in vitro. Rinse in 1% KOH.

CAUTION: Avoid contact and inhalation. The reaction is birefringent. And I wonder if the concentration of L-ascorbic acid is correct, since I have found a lot of heterogeneity of this concentration in the bibliography. Cells were then fed twice weekly and left for 21 or 28 days before being washed with PBS and fixed in 10% PFA for 30 minutes. All fetuses are removed from the mother by … What is the best pH of Alizarin Red S staining with Calcium in osteogenesis differentiation of MSCs? I am not surprised that the monolayer is hard to disrupt, because of the very rich deposit of ECM being produced by the differentiating cells.
