Validation of a PCR coupled to a microarray method for detection of mycoplasma in vaccines

The revised section of the European, United States, and Japan Pharmacopeias on mycoplasma testing provided guidance for the set up and validation of a nucleic acid amplification technique (NAT) as an alternative method to agar culture and indicator cell culture compendial methods. The CytoInspect™ method, based on Polymerase Chain Reaction (PCR) coupled to microarray analysis, has been selected for detection and identification of mycoplasma in vaccines. To replace compendial methods, the alternative method must demonstrate equivalence in both limit of detection (LOD) and specificity compared with compendial methods. Here, we summarize the validation of the CytoInspect™ method according to current pharmacopeia requirements. Validation of the robustness, sensitivity (at least 10 colony forming units/ml) and specificity of the CytoInspect™ method are demonstrated. Likewise, a comparability study was performed to compare the LOD for CytoInspect™ compared with the previously validated LOD for compendial culture tests.
