A Rapid and Sensitive Nucleic Acid Amplification Technique for Screening of Cell Therapy Products.

species (spp.) bacteria can infect cell cultures, posing a potential threat to recipients of cell therapy products. Conventional testing methods are highly sensitive but typically require a minimum of 28 days to produce results. This delay is problematic if rapid results are needed to inform treatment decisions. Nucleic acid amplification technique (NAT) methods have been gaining favor for testing due to their speed and specificity; however, they must first be qualified as meeting or exceeding the sensitivity of the compendial method. We present herein a NAT method for the detection of that circumvents the need for live spp. in the test procedure by instead being qualified using spp. genomic DNA. We have demonstrated a lower limit of detection that exceeds the regulatory requirements set by Health Canada. This assay is now being used to screen clinical cell therapy products manufactured at our center.
