PR1MA qMAX One-Step RT-qPCR Kits

  • RNA to cDNA to qPCR in one tube
  • High purity enzyme formulation for enhanced stability and performance
  • PR1MA Hot-Start Taq allows for preparation at room-temperature
  • Compatible with all qPCR instruments
  • Available for green fluorescence or probe detection
PR1MA qMAX One Step Kits allow for highly sensitive real time RT-qPCR assays to be performed directly from RNA templates.  Workflows are simplified with optimized formulations of ready-to-use 2X qPCR master mix and reverse transcriptase. Optimized buffer includes powerful RNase inhibitors and an extremely thermostable MMLV-derived reverse transcriptase enables robust first strand cDNA synthesis.  PR1MA Hot Start Taq uses an antibody mediated hot start mechanism allowing for sample preparation at room temperature.  Only after an initial incubation at 95°C will the Taq become active, so non-specific amplification is greatly reduced.  An inert blue dye is included in the Taq master mix to help simplify pipetting and reduce errors.

Both One-Step Kits are compatible with standard and fast cycling protocols and provide increased sensitivity, speed and reproducibility for a broad range of samples and targets.  The polymerase mix is available with different levels of ROX reference dye for compatibility with all qPCR instruments.

Two versions of our One-Step qPCR Kits are available:

PR1MA qMAX Green One-Step Kits incorporate our proprietary intercalating dye which exhibits higher fluorescent and lower PCR inhibition than other popular dyes such as SYBR.

PR1MA™ qMAX Probe One-Step Kits are optimized for use with popular TaqMan, Scorpions, and molecular beacon probes.

  • DNA extraction and amplification in 1 hour
  • Proprietary lysis buffer optimized for ear punches, tail snips and other mammalian tissues
  • Single tube - no organic solvents or clean up procedures
  • Enhanced PR1MA Hot Start Polymerase included

Traditionally, mammalian genotyping protocols have involved Proteinase K digestion, neutralization, organic extraction and lots of hands on time to get PCR-ready DNA.

The PR1MA Mammalian Genotyping Kit is quick and easy to use - add sample to the proprietary lysis buffer and incubate for 5-10 minutes, then add the deactivation buffer and incubate for 10 minutes. The crude lysate can then be amplified using fast PCR PR1MA Hot Start Taq Master Mix with red loading dye (included). The kit contains everything needed - just add sample and primers.
