Surface Survival & Environmental Persistence Risk Assessment for Live Microbes

Yes. While traditional CFU plating evaluates cells capable of active replication under specific conditions, adding qPCR or PMA-qPCR provides a complementary perspective. Stressed cells on surfaces may sometimes lose culturability while retaining intact membranes. Offering dual readouts ensures you have a comprehensive understanding of both actively growing biomass and residual biological signals.

Absolutely. Our risk evaluation platform is highly modular. If your facility utilizes specialized materials (e.g., specific cleanroom epoxy grades, proprietary tubing) or relies on custom-formulated cleaning agents, you can provide these materials to us. We will incorporate them directly into the experimental protocol to ensure the data perfectly reflects your real-world handling scenarios.

We regularly handle strict anaerobes and oxygen-sensitive live biotherapeutics. Our facilities are equipped with specialized anaerobic workstations and controlled chambers. In fact, evaluating oxygen exposure is often a key parameter requested by clients to understand the natural decay rate of anaerobes when accidentally exposed to standard aerobic cleanroom environments.

The quantitative readouts from our studies—such as decay kinetics and chemical reduction baselines—form a robust foundation for your development-stage risk documentation. This objective data is highly useful for internal quality reviews, drafting effective standard operating procedures (SOPs), and facilitating productive, evidence-based discussions with CDMO partners regarding facility onboarding and cross-contamination mitigation.
