The PR2120-N-S is the trial / sample-size SKU of the Accuris qMAX Green No ROX One-Step RT-qPCR Kit family — 20-reaction pack for first-use evaluation on Bio-Rad CFX / Roche / Stratagene Mx / Eppendorf / Qiagen cyclers (the dominant research-grade cycler family).
Pack-quantity note: The universe label specifies 20 reactions for the No ROX sample (vs 10 reactions for the sister H / L variant samples) — confirm pack quantity at order. The discrepancy may reflect a labeling-update difference between ROX variants.
For complete chemistry rationale, see the PR2120-H-100 parent page.

Probe vs Green Sample Pairing
Pair with PR2121-N-S (qMAX Probe One-Step RT-qPCR No ROX sample) for Green vs Probe One-Step RT-qPCR chemistry comparison on Bio-Rad CFX (or other No ROX cycler) — supports the dual-chemistry workflow evaluation for labs evaluating the full Accuris qMAX RT-qPCR product line.
Application Profile
See PR2120-H-100 parent page for the full application profile.
Ordering & Configuration
Single-use sample SKU. 20-reaction pack supports a comprehensive One-Step RT-qPCR validation run.
Pair with RNA template + sequence-specific primers. Operator supplies RNA template and primers.
Cycler-compatibility confirmation. Critical that No ROX matches the cycler.
Storage. -20 °C, RNase-free handling, protect from light.
Confirm at quote: cycler model and ROX requirement (No ROX confirmation), evaluation intent (Green-only vs Green+Probe chemistry comparison), and lead time.
Warranty: Per Accuris standard reagent terms — confirm at quote.
Accuris qMAX Green One-Step RT-qPCR sample triad:
- PR2120-N-S (this product) — No ROX (Bio-Rad CFX / Roche / Stratagene Mx / Eppendorf / Qiagen)
- PR2120-L-S — Low ROX
- PR2120-H-S — High ROX
Pick the No ROX sample for Bio-Rad CFX-based labs (largest installed-base) or other non-ABI cyclers.
