Accuris High Fidelity Master Mix, 200 Reactions

The PR1001-HF-200 is the single-tube 2X High Fidelity master mix, sold as 200-reaction pack (2 × 1.25 mL tubes) per the Accuris Life Science Reagents Catalog. The HF master mix integrates the proofreading high-fidelity polymerase + buffer + dNTPs + MgCl₂ into a single tube, supporting the blunt-end PCR product workflows (TA cloning, blunt-end ligation) where proofreading polymerase produces blunt-end products vs standard Taq's 3' A-overhang.

Pack-format note: The HF master mix ships in 2 × 1.25 mL tubes for 200 reactions, different from the standard Taq 2X master mix (PR1001-200) which ships in 4 × 1.25 mL tubes for the same 200 reactions. The HF master mix runs at higher per-reaction volume (12.5 µL of 2X mix per reaction vs the standard Taq's 6.25 µL; confirm exact recommended per-reaction volume in the product insert).

Key Specifications

Per Brochure HF Master Mix Applications

Per Accuris Life Science Reagents Catalog, High Fidelity Master Mix applications include:

• Blunt-end / TA cloning. HF polymerase produces blunt-end PCR products that can be either ligated into blunt-end vectors directly, or treated for TA cloning workflows
• Colony PCR. When colony screening feeds into downstream sequencing-grade workflow
• Fast PCR. Short-amplicon HF amplification with reduced cycle times
• GC- and AT-rich DNA amplification. HF chemistry handles extreme-composition templates better than standard Taq
• Low Copy PCR. Sensitive PCR from low-copy template benefits from HF's reduced error accumulation across cycles

HF Master Mix vs HF Standalone Polymerase

The Accuris HF chemistry is available in both formats:

Same chemistry, different workflow profile. Pick the master mix for setup convenience; pick the standalone for per-reaction cost optimization at scale.

HF vs HF + Hot Start Master Mix Selection

The PR1001 HF master mix family includes two related master mix formats:

Pick the HF-only master mix when: the workflow benefits from HF accuracy (cloning, sequencing prep, mutagenesis) but the lab does not require hot-start chemistry's pre-activation suppression. Pick HFHS for workflows needing both.

Application Profile

Blunt-end PCR product cloning. The workhorse HF application. Blunt-end ligation workflows benefit from HF polymerase's blunt-end product chemistry.

Sequencing-prep PCR. Fragment-extraction prep for Sanger or NGS library construction benefits from HF accuracy.

Site-directed mutagenesis. Workflows where preserving template sequence accuracy matters benefit from HF chemistry's low error rate.

GC- and AT-rich amplification. Extreme-composition templates benefit from HF chemistry over standard Taq.

Low-copy PCR. Sensitive PCR from low template benefits from HF's reduced cumulative error.

Microarray template prep. Workflows where sequence accuracy matters for downstream microarray analysis.

Multi-operator HF workflows. Facilities running HF on shared benches benefit from the master-mix format's reduced setup-variability across operators.

Ordering & Configuration

Per-reaction workflow consumable. Each PCR reaction uses 12.5 µL of the 2X HF master mix (confirm exact volume in product insert). A 1.25 mL tube supports 100 reactions at 12.5 µL each; the 200-reaction pack is 2 × 1.25 mL tubes.

Storage. HF reagent storage applies. Confirm storage protocol at order.

Pair with template / primers / water. The master mix includes the polymerase + buffer + dNTPs + MgCl₂; operator supplies template, primers, and water (or PCR-grade buffer).

Confirm at quote: workflow PCR throughput (drives 200-rxn vs 500-rxn pack-size selection), HF vs HFHS decision (does the workflow need hot-start control), evaluation interest (PR1001-HF-S sample at $7.65 for first-use validation), and lead time.
