| Catalog No. | RERE-0278 |
| Description | Strong alizarin red S preparation at 1 percent held at pH 4.2, using dye of CAS 130-22-3. The weakly acidic environment limits non-specific background while still permitting calcium chelation, a combination often chosen for tissue blocks with abundant mineral. Deposits take the familiar orange red tone and the reagent keeps 12 months at room temperature in the dark. |
| Intended Use | Calcium staining where an acidic working pH is specified by the protocol |
| Principle / Technology | Alizarin red S chelates calcium salts in weakly acidic solution to give an orange red product |
| Specificity | 1 percent; pH 4.2; CAS 130-22-3; 12 month shelf life |
| Reaction Conditions / Protocol | Apply to the specimen, allow the reaction to proceed with microscopic control, then rinse and mount |
| Storage Conditions | Room temperature, protected from light |
| Package Specifications | 100 mL |
