Abstract

Although novel retroviral vectors for use in gene-therapy products are reducing the potential for formation of replication-competent retrovirus (RCR), it remains crucial to screen products for RCR for both research and clinical purposes. For clinical-grade gammaretrovirus-based vectors, RCR screening is achieved by an extended S+ L- or marker-rescue assay, whereas standard methods for replication-competent lentivirus detection are still in development. In this report, we describe a rapid and sensitive method for replication-competent gammaretrovirus detection. We used this assay to detect three members of the gammaretrovirus family and compared the sensitivity of our assay with well-established methods for retrovirus detection, including the extended S+ L- assay. Results presented here demonstrate that this assay should be useful for gene-therapy product testing.
