| Product Name | Alizarin Red S Staining Solution, 0.1%, pH 8.3 |
| Catalog No. | RERE-0274 |
| Description | Dilute alizarin red S solution, 0.1 percent and buffered to pH 8.3, prepared from dye of CAS 130-22-3. At this mildly alkaline pH the dye chelates calcium efficiently, and the supplier notes that dilute alizarin red S tends to deliver more reliable staining when only small amounts of deposit are present. This makes the reagent a frequent choice for osteogenic differentiation assays. Shelf life is 6 months with light protection. |
| Intended Use | Staining of small calcium deposits in mineralizing cultures and tissue sections |
| Principle / Technology | At pH 8.3 alizarin red S forms an orange red chelation complex with calcium salts |
| Specificity | 0.1 percent; pH 8.3; CAS 130-22-3; 6 month shelf life |
| Reaction Conditions / Protocol | Cover the specimen with the solution for the recommended interval, monitor microscopically, rinse and mount |
| Storage Conditions | Room temperature, protected from light |
| Package Specifications | 100 mL |
| Key Features | Low dye concentration favors small-deposit detection; pH 8.3 supports chelation chemistry; 6 month shelf life |
