PCR Biosystems launches Lyo-Ready Inhibitor-Tolerant reagents expanding robust performance to lyophilised qPCR and RT-qPCR workflows
PCR Biosystems today announced the launch of its new Lyo-Ready Inhibitor-Tolerant reagents, bringing the company’s powerful inhibitor-tolerant chemistry into its growing range of lyophilisation-ready reagents for molecular diagnostics.
This new product line enables developers to build highly stable, ambient-temperature assays without compromising performance in challenging sample types such as blood, saliva, and other inhibitor-rich matrices.
Inhibitor-tolerant performance, now in a lyophilisation-ready format
PCR Biosystems’ inhibitor-tolerant chemistry has already been widely adopted for high-performance PCR and qPCR in complex biological samples. By integrating this chemistry into a lyo-ready 4x master mix, the company now provides diagnostic developers with reagents that withstand inhibitors and support room-temperature stability after drying.
The result is a flexible reagent platform that simplifies upstream sample preparation and supports dependable amplification even when sample extraction is limited.
Ideal for real-world diagnostics using blood and saliva samples
Blood and saliva are increasingly being used in non-invasive diagnostic workflows, but both contain compounds known to hinder qPCR and RT-qPCR reactions. By resisting these inhibitors, the Lyo-Ready mixes help minimise false negatives, preserve sensitivity, and improve assay reliability in direct or minimally processed workflows. This makes the mixes particularly valuable for decentralised testing environments, high-throughput public health programmes, and point-of-care applications.
Designed for ambient storage, simplified logistics and global reach
As fully lyo-ready, glycerol-free formulations, the new mixes are engineered for drying without additional optimisation. Once lyophilised, the reagents can be shipped and stored at ambient temperatures, removing the need for cold-chain infrastructure and reducing logistical complexity across global supply routes. This ambient stability enables diagnostic developers to create dried assay kits that are well suited for resource-limited laboratories, decentralised testing settings, and workflows where simplified storage and transport are essential.
Two formats for complete DNA and RNA detection workflows
The product range includes:
- Lyo-Ready Inhibitor-Tolerant Probe Mix – For high-sensitivity DNA detection in probe-based qPCR.
- Lyo-Ready Inhibitor-Tolerant Probe 1-Step Kit – A complete 1-step RT-qPCR solution for RNA detection, featuring a high-concentration UltraScript® reverse transcriptase and RNase inhibitor for strong performance in demanding assays.
Both mixes are 4× concentration, glycerol-free, and pre-blended with lyophilisation-compatible excipients, ensuring high activity after resuspension and reliable performance across diverse assay formats.
Built for singleplex and multiplex testing
Whether developing a targeted single-gene assay or a multi-pathogen diagnostic panel, the new mixes deliver strong, reproducible amplification with excellent probe compatibility. Their tolerance to inhibitors paired with lyophilisation-readiness makes them highly suited to multiplexed diagnostic tests intended for broad, real-world deployment.
“Achieving consistent results from complex biological samples remains a major challenge for assay developers,” said Alex Wilson, Co-Founder at PCR Biosystems. “Our new Lyo-Ready Inhibitor-Tolerant reagents bring together inhibitor tolerance and lyo-ready stability to deliver high-sensitivity qPCR and RT-qPCR across a wide range of challenging workflows, without compromising performance.”
The Lyo-Ready Inhibitor-Tolerant Probe Mix and Probe 1-Step Kit are now available for quotes and sample evaluation. PCR Biosystems offers full technical support, custom formats, bulk supply and OEM manufacturing options for diagnostic developers.
