Is Alizarin Red Light Sensitive?
Calcium hydroxyapatite crystals are not visible with light microscopy (75 to 250 nm), and are nonbirefringent in polarized light. Alizarin red S stain is a sensitive but nonspecific tool for screening for calcium hydroxyapatite crystals.
How do I make Alizarin Red stain?
Alizarin Red S Solution preparation: Dissolve 2 g Alizarin Red S (Sigma, Cat# A5533) in 100 ml of ddH2O and adjust pH to 4.1-4.3 with HCl or NH4OH. Filter the solution through 0.22 µ membrane and store at 4oC in dark.
Which type of dye is alizarin?
Alizarin is a red dye found in the roots of the madder plant and the powdered roots are used directly in the dyeing process.
How will you prepare alizarin?
Preparing alizarin is quite a complex process. It’s prepared using a mixture of sodium perchlorate, water, potassium hydroxide, and anthraquinone. The mixture is heated in an oil bath at 200 °C, then cooled and dissolved in water.
How do you make a red O oil solution?
Oil Red O: To make Oil Red O Stock Solution, dissolve Oil Red O in 20 ml of 100% isopropanol, mix well and let it sit for 20 min. Stable for 1 year. To make Oil Red O Working Solution, add 3 parts of Oil Red O Stock Solution to 2 parts of dH2O, mix well, and allow to sit for 10 min.
How do you make osteogenic media?
Finally, the experimental osteogenic medium was prepared by adding 10% FBS, 0.01 μM dexamethasone, 50 μg/mL ascorbic acid, 10 mM sodium β-glycerophosphate, 10,000 U/mL penicillin, and 10,000 U/mL streptomycin to the experimental culture medium.
How is alizarin produced?
alizarin, also spelled Alizarine, a red dye originally obtained from the root of the common madder plant, Rubia tinctorum, in which it occurs combined with the sugars xylose and glucose.
Why alizarin is used as a mordant dye?
The most important use of alizarin in modern times is as a staining agent in biological research because it stains free calcium and certain calcium compounds.
What is oil red O staining used for?
Background: Oil Red O, a stain commonly used to demonstrate lipid in frozen tissue, also may be used to stain air-dried cytologic specimens.

| Nuclei | Blue |
What is osteogenic induction?
To efficiently drive differentiation of mesenchymal stem cells (MSCs) to osteocytes.
What is differentiation medium?
Differentiation medium promotes cells to change from one type to another, often a less specialized type becoming more specialized in form and function, while Induction medium provides signals that change cell behavior, shape, differentiation, mitotic activity, signal cascades and/or gene expression.
Is alizarin a mordant dye?
Hint: We know that Alizarin is a mordant dye which is mainly used in the dyeing purposes. It is also used in hand block printing technique.
What does Sudan IV stain?
Sudan IV (C24H20N4O) is a lysochrome (fat-soluble dye) diazo dye used for the staining of lipids, triglycerides and lipoproteins on frozen paraffin sections. It has the appearance of reddish brown crystals with melting point 199 °C and maximum absorption at 520(357) nm.
What does H and E stain?
H and E staining helps identify different types of cells and tissues and provides important information about the pattern, shape, and structure of cells in a tissue sample. It is used to help diagnose diseases, such as cancer. Also called hematoxylin and eosin staining.
What is Oil Red O staining used for?
What type of stain is Oil Red O?
Oil Red O is a fat-soluble dye that stains neutral triglycerides and lipids. It cannot be used with formaldehyde-fixed paraffin embedded sections as the alcohols used remove most lipids.
