The PR1000-S is the trial / sample-size SKU of the Accuris standard Taq DNA Polymerase family — 50 units of standard Taq at 5 U/µL (10 µL total) for first-use evaluation of the Accuris Taq chemistry before committing to the larger production-scale packs. list price, the sample SKU enables labs to validate the Accuris Taq performance on their specific PCR target before scaling procurement.

Three Sample Packs — Compare All Three Chemistries
Accuris offers three matched-price sample packs for first-use evaluation across the three PR1000 polymerase chemistries:
| Sample SKU | Chemistry | Trial reactions | Production-scale follow-on |
| PR1000-S (this product) | Standard Taq | ~25–50 | PR1000-500 / -1000 / -6000 |
| PR1000-HS-S | Hot Start Taq | ~25–50 | PR1000-HS-500 / -1000 / -6000 |
| PR1000-HF-S | High Fidelity | ~10 | PR1000-HF-200 / -1000 |
Procurement strategy. Labs new to Accuris reagents can order all three sample packs for a complete chemistry comparison on the lab's specific PCR targets — supports informed bulk-procurement decisions across the polymerase family.
Standard Taq vs Hot Start vs HF Decision
| Feature | PR1000 Standard Taq (this sample) | PR1000-HS Hot Start | PR1000-HF High Fidelity |
| Polymerase concentration | 5 U/µL | 5 U/µL | 2 U/µL |
| Hot-start activation | None — active at all temps | Antibody-mediated | None |
| Proofreading | No | No | Yes — 3'→5' exonuclease |
| Error rate | ~1×10⁻⁴ | ~1×10⁻⁴ | ~1×10⁻⁶ |
| Best fit | Routine endpoint PCR, colony PCR, screening | Multiplex, GC-rich, low-copy | Cloning, sequencing-prep, mutagenesis |
Pick standard Taq when: the workflow is routine, well-optimized endpoint PCR where neither hot-start nor high-fidelity premiums are justified by the workflow's specific requirements.
Per Brochure Standard Taq Applications
Per Accuris Life Science Reagents Catalog, standard Taq applications include:
- Colony PCR — direct PCR from bacterial colony for clone screening
- Fast PCR — short-amplicon PCR with reduced cycle times
- Genotyping — endpoint PCR for SNP and indel genotyping workflows
- High-throughput PCR — production-scale endpoint PCR for screening or diagnostics
- Routine PCR — general-purpose endpoint amplification
Application Profile
Standard Taq chemistry first-time evaluation — labs evaluating Accuris standard Taq for the first time use the sample pack to validate fit before bulk procurement.
New PCR-target validation — labs adding standard Taq to a new amplicon validate the protocol on the sample pack before committing.
Multi-chemistry comparison — labs evaluating standard / Hot Start / HF chemistry trade-offs run all three sample packs in parallel for direct comparison.
Sales / training samples — sales reps and training programs use the sample pack for hands-on customer demonstrations.
Educational laboratory PCR exercises — molecular-biology coursework introducing standard PCR chemistry on a per-class budget.
Ordering & Configuration
Single-use sample SKU. The 50-unit pack supports a multi-condition validation run; not intended for routine production use.
Pair with dNTPs. Standard Taq buffer does not include dNTPs (unlike HF buffer) — confirm dNTP inventory at order. dNTPs sold separately.
Confirm at quote: standard Taq evaluation intent (vs production-pack ordering), production-pack interest (PR1000-500 / -1000 / -6000 follow-on), comparison to Hot Start / HF (all three samples available each), and lead time.
Warranty: Per Accuris standard reagent terms — confirm at quote.
