The PR2121-N-100 is the No ROX formulation of the Accuris qMAX Probe One-Step RT-qPCR Kit — sold as 100-reaction entry pack. Same probe-based RT + qPCR single-tube chemistry as the High / Low ROX sister variants, with no passive reference dye for cyclers that don't use ROX normalization (Bio-Rad CFX, Roche LightCycler, Eppendorf realplex, Stratagene Mx, Qiagen Rotor-Gene — the largest research-grade qPCR cycler installed-base).
For complete chemistry rationale, see the PR2121-H-100 parent page.
