| Product Name | Alizarin Red S Staining Solution, 2%, pH 4.2 |
| Catalog No. | RERE-0290 |
| Description | High-strength alizarin red S formulation combining a 2 percent dye load with a pH 4.2 buffer, based on dye of CAS 130-22-3. The acidic working environment restrains non-specific background while the concentrated dye drives rapid chelation of calcium salts, an efficient pairing for specimens that carry dense mineralization. Deposits take the characteristic orange red color within short staining windows. Shelf life is 12 months at room temperature with light protection. |
| Intended Use | Rapid chelation staining of calcium-rich, densely mineralized specimens under acidic conditions |
| Principle / Technology | Alizarin red S chelates calcium salts in weakly acidic solution to form an orange red complex |
| Specificity | 2 percent; pH 4.2; CAS 130-22-3; 12 month shelf life |
| Reaction Conditions / Protocol | Apply the solution to the specimen with microscopic monitoring, rinse once the color has fully developed and mount |
| Storage Conditions | Room temperature, protected from light |
| Package Specifications | 100 mL |
| Key Features | Top dye concentration with acidic buffering; short staining times on mineral-heavy samples; 12 month shelf life |
