Replication-Competent Virus (RCV) and Replication-Competent Lentivirus (RCL) testing is a critical safety requirement in gene therapy development. These tests ensure that viral vectors used in gene therapies are free from replication-capable viruses, which is essential for patient safety and regulatory compliance. At Creative Biolabs, we provide comprehensive RCV/RCL testing services with state-of-the-art facilities and extensive expertise in viral vector safety assessment. Our testing services are designed to meet the stringent requirements of global regulatory authorities, including FDA, EMA, and NMPA. With our advanced testing platforms and experienced scientific team, we ensure reliable and accurate testing results to support your gene therapy development journey.
RCV/RCL testing encompasses sophisticated analytical methods designed to detect and quantify replication-competent viruses in gene therapy products. The testing process involves multiple complementary techniques, all working together to identify any virus particles that may have regained their ability to replicate independently.
The presence of replication-competent viruses can lead to severe consequences:
Replication-competent viruses can cause serious clinical complications:
Regulatory authorities mandate comprehensive testing throughout development:
Comprehensive safety measures include:

Our Replication-Competent Virus Testing Services are applicable to various types of samples, including:
The sensitivity of our replication-competent virus testing services depends on the specific detection method employed:
We select the most appropriate testing methods based on our clients' specific requirements, and we can combine multiple methods when necessary to achieve optimal detection performance. We continually validate and improve our testing methods to ensure the highest levels of sensitivity and reliability.
Yes, many of our detection methods can simultaneously detect multiple viruses:
We can develop customized multiplex detection methods tailored to the target virus types provided by our clients, fulfilling the need to detect multiple viruses concurrently.
