[Research Use] SENSIFAST Probe One-Step for FAST . SENSITIVE . REPRODUCIBLE Results

The SensiFAST™ Probe One-Step Kits have been formulated for highly reproducible first-strand cDNA synthesis and subsequent real-time PCR in a single tube and uses a combination of the latest advances in buffer chemistry and enhancers, together with an antibody-mediated hot-start DNA polymerase system, to ensure fast, highly-specific and ultra-sensitive one-step RT-qPCR. This also gives SensiFAST Probe One-Step unbeatable efficiency in multiplexing.

  • Novel 1-step buffer optimized for highly-efficient RT and PCR steps
  • Improved consistency between technical replicates
  • Reproducible, accurate results in as little as 40 minutes
  • Antibody-mediated hot-start minimizes non-specific amplification
  • Excellent efficiency for improved multiplexing

[Molecular Assay Development] Novel RT-qPCR Reagent Solutions for Fast and Accurate Screening Assays

Diagnostic companies and laboratories in China have turned to Meridian’s Lyo-Ready 1-Step RT-qPCR Mix to develop fast and accurate screening assays for 2019-nCoV in response to the outbreak.

Fast 1-Step RT-qPCR Mix

  • Formulated for fast, automated, high-throughput systems
  • Sensitive detection of low-copy number DNA and RNA targets
  • Highly suited to multiplex assays from a broad range of sample types

Lyo-Ready 1-Step RT-qPCR Mixes

  • Provided glycerol-free and pre-formulated with a specialized blend of lyo-excipients
  • Virus mix (Cat #MDX062) is specifically optimized for amplification of RNA or DNA viruses with a high secondary structure (reverse transcriptase remains active at 55-60 °C)
  • Suited for multiplex-assays and low-copy number targets • Compatible with lyophilization into beads or cakes
  • Ideal for developing fast, highly reproducible assays requiring ambient temperature transport and storage

Japan NIID Recommended Reagents

There are two methods established by National Institute of Infectious Diseases (NIID), qualitative detection by nested PCR method and alternatively, real-time one-step probe based RT-qPCR method.

Quick Taq® HS Dyemix (Code No. DTM-101) was used to perform the nested PCR outline in the published manual.

  • Enables greater PCR performance than conventional Taq DNA polymerase.
  • anti-Taq antibodies for hot start PCR. Hot start technology realizes highly specific and sensitive PCR
