| Product Name | Alizarin Red S Staining Solution, 0.2%, pH 4.2 |
| Catalog No. | RERE-0287 |
| Description | Acidic alizarin red S formulation at 0.2 percent and pH 4.2, prepared from dye of CAS 130-22-3. The slightly higher dye load relative to the 0.1 percent grade shortens staining times while the acidic buffer restrains non-specific coloration, a balance useful for mineralized matrices with moderate deposit density. Shelf life is 12 months at room temperature with light protection. |
| Intended Use | Calcium deposit staining under specified acidic conditions |
| Principle / Technology | The dye chelates calcium in weakly acidic solution, giving orange red deposits |
| Specificity | 0.2 percent; pH 4.2; CAS 130-22-3; 12 month shelf life |
| Reaction Conditions / Protocol | Apply the solution, observe color development under the microscope, rinse and mount |
| Storage Conditions | Room temperature, protected from light |
| Package Specifications | 100 mL |
| Key Features | Mid-range dye strength for moderate deposit loads; acidic buffer keeps background low; 12 month shelf life |
