Medchemexpress LLC Alizarin red S sodium | 130-22-3 | 95.0% | 100 MG
Alizarin Red S sodium is the sodium salt of the anthraquinone dye Alizarin Red S, used to detect and stain calcium deposits and mineralized matrices in biological samples. It binds calcium ions to produce an orange-red signal and exhibits fluorescence (Ex/Em ~500/570 nm). Supplied as a solid with typical purity around 95.0%, recommended storage is sealed at 4°C; solutions may be stored at -80°C (up to 6 months) or -20°C (up to 1 month).
- Detects and stains calcium deposits in tissues and cell cultures.
- Useful for osteoblast differentiation assays and histological bone staining.
- Excitation/emission approximately 500/570 nm for fluorescence detection.
- Supplied as a light yellow to brown solid with ~95.0% purity.
- Store sealed at 4°C and protect from moisture and light; follow solvent storage guidance for solutions.
