| Product Name | Saliva Collection and Preservation Buffer, DNA Optimized |
| Catalog No. | ATR-SPS-0015 |
| Description | A specialized preservation buffer for the collection, transport, and stabilization of genomic DNA from human saliva specimens, enabling room temperature storage for extended periods. |
| Intended Use | Stabilization of genomic DNA in saliva samples for genetic testing, GWAS studies, ancestry analysis, and consumer genomics applications without immediate refrigeration. |
| Principle / Technology | Denaturing agents inactivate nucleases and lyse buccal epithelial cells; chelating agents bind divalent cations; antimicrobials prevent bacterial overgrowth; DNA is stabilized for long-term room temperature storage. |
| Detection Method | DNA yield and purity by spectrophotometry, DNA integrity by pulsed-field gel electrophoresis, storage stability up to 5 years |
| Sample Type | Human saliva, buccal swabs |
| Performance Range / Specifications | DNA yield 20–200 µg per 2 mL saliva; A260/A280 1.7–1.9; DNA stable at room temperature for >2 years |
| Sensitivity / LOD | N/A |
| Specificity | N/A |
| Reaction Conditions / Protocol | Donor provides 2 mL saliva into collection tube containing buffer; cap and mix thoroughly by inversion; DNA remains stable at room temperature until extraction. |
| Components / Formulation | Tris buffer, EDTA, SDS, sodium chloride, proprietary antimicrobial cocktail |
