| Product Name | Unique Dual Index Primers for Illumina Tagmentation Libraries |
| Catalog No. | NG-QCY-0050 |
| Description | Unique dual-index primer sets for tagmentation-based DNA or RNA library preparation. Independent i5 and i7 index combinations help reduce index hopping and index misassignment during multiplex sequencing. |
| Intended Use | Tagmentation-based DNA/RNA library preparation, ATAC-seq, CUT&Tag, high-throughput sequencing and automated library construction. |
| Principle / Technology | Dual-index PCR amplification adds two independent sample identifiers to each library. |
| Detection Method | High-throughput sequencing. |
| Sample Type | Tagmentation-prepared DNA or RNA libraries. |
| Performance Range / Specifications | Up to 384 unique dual-index combinations; cross-contamination rate ≤0.1%; library-yield variation among indexes within ±20%. |
| Specificity | Independent dual indexes improve sample assignment accuracy in multiplex sequencing. |
| Reaction Conditions / Protocol | Add the selected dual-index primer combination during library amplification according to the compatible tagmentation workflow. |
| Components / Formulation | Tube-format unique dual-index primers or four 96-well index-primer plates. |
| Storage Conditions | Store under the low-temperature conditions specified for sequencing oligonucleotide reagents. |
| Package Specifications | 24 reactions; 96 reactions. |
| Product Form | Indexed primer set in tube or plate format. |
| Quality Control | Index combinations are functionally verified for library yield, uniformity and low cross-contamination. |
| Key Features | 384 index combinations; single-addition workflow; low index crosstalk; suitable for automation and high-throughput sequencing. |
| Compatibility | Illumina sequencing workflows and compatible tagmentation-based library preparation systems. |
| Application Notes / Precautions | Use index combinations appropriate for the planned pooling design and sequencing instrument. |
| Batch-to-Batch Consistency | Index performance and cross-contamination are controlled during release testing. |
For research use only, not for clinical use.
