Liquid Ambient-Stable Master Mixes

Ambient Temperature Stability Redefined

Meridian’s liquid qPCR master mixes set a new standard for stability and performance, preserving amplification activity for more than 12 months at 15 – 25°C. This breakthrough gives assay developers the freedom to design, manufacture and distribute assays without cold chain costs, transport risks or delays. For end users in hospitals, reference labs and point-of-care settings, it provides confidence in reliable, ambient temperature storage with consistent performance.

Traditional liquid mixes degrade rapidly in ambient conditions, leaving developers with two costly options: refrigerated shipping and storage or conversion to dry formats such as lyophilization. Both add expense, extend timelines, and complicate workflows. Meridian’s formulations overcome these barriers, maintaining full performance without freezing or drying while streamlining processes and enabling faster, more efficient test deployment.

Two Flexible Formats for Different Needs:

• Liquid Stable Ready Mix (MDX364): A qPCR master mix with 12-month ambient-temperature stability and proven resilience for more than two weeks at 50 °C. Designed for direct primer and probe addition at the point of manufacture, MDX364 eliminates refrigeration and lyophilization while enabling rapid, scalable and cost-effective assay production.
• Liquid Stable Flex Mix (MDX360): A qPCR master mix with 12-month ambient-temperature stability that allows primers and probes to be added at the point of use, providing greater flexibility in assay design and setup. MDX360 reduces operational costs, supports batching, minimizes hands-on time and enables faster turnaround for both high-throughput and decentralized testing environments.
