mycoplasma detection diagram

Why is mycoplasma testing necessary for GMP manufacturing?

Mycoplasmas, the smallest known free living organisms, are relatively common and difficult to detect bacterial contaminants of mammalian cell cultures. In therapeutic applications, an undetected mycoplasma contamination can negatively impact product quality and patient safety. GMP manufacturers develop stringent risk mitigation plans to ensure early detection of mycoplasmas to avoid costly manufacturing delay or remediation activities. For lot-release testing, regulatory guidance requires that all products derived from cell culture be tested for the presence of mycoplasma.

Requirements for regulatory acceptance

For mycoplasma detection assays, regulatory agencies require validation studies to confirm the sensitivity, specificity, and robustness of the method to meet their standards. The MycoSEQ detection assay has achieved such success through demonstrating these parameters:

Proven specificity of the MycoSEQ Detection Assay:

The MycoSEQ kit has been validated in numerous independent studies to specifically detect a wide variety of Mycoplasma, Acholeplasma, and Spiroplasma species with no known cross-reactivity with closely related bacterial species. Specificity testing results and bioinformatics analysis are detailed in the Drug Master File (DMF) which is filed with the United States Food and Drug Administration (FDA) and Health Canada.

High sensitivity of the MycoSEQ Detection Assay:

Internal and external validation methods have demonstrated limit of detection (LOD) to meet or exceed the recommended regulatory guidance of 10 CFU/mL, or the genomic equivalent of 10 genome copies (GC)/mL for a vast panel of mycoplasma species including those known to contaminant bioprocessing cultures.

Robustness of the MycoSEQ Detection Assay:

Deliberate variations in the method parameters have been extensively evaluated by Thermo Fisher Scientific as part of the assay development process and validated by independent studies.

AccuSEQ software, QuantStudio 5, MycoSEQ mycoplasma detection qPCR testing

Software to help enable 21 CFR Part 11 compliance

The Applied Biosystem AccuSEQ Real-Time Detection Software is designed to work with the QuantStudio 5 Real-Time PCR instrument or the 7500 Fast Real-Time PCR instrument. Dedicated templates and data analysis algorithms allow for easy plate set up and automated mycoplasma presence-absence calling. Security, audit, and e-signature features enable 21 CFR Part 11 compliance.

Highlights

  • Optimized and validated for the MycoSEQ Mycoplasma Detection assay
  • Easy visual result summary provides immediate understanding of presence or absence of mycoplasma in your samples
  • Confidence in positive results with automated detection of discriminatory positive control (DPC)
  • Robust data analysis parameters for the MycoSEQ Mycoplasma Detection assay (Ct, Tm, and DV values)
  • Security, audit, and signature capabilities to enable 21 CFR Part 11 compliance

The AccuSEQ software features an intuitive interface that provides an easy way to identify presence or absence of mycoplasma. The software demonstrates one of the key parameters.

Designed for purpose using a multi-parameter analysis

Three distinct assay acceptance criteria provide confidence in the determination of the presence or absence of mycoplasma. The cycle threshold (Ct) value indicates that amplification has occurred, while melting temperature (Tm) and derivative value (DV) confirm that amplification was due to mycoplasma DNA. All three criteria must meet specific values established during validation for a test sample to be positive for the presence of mycoplasma DNA.

Mycoplasma detection sensitivity and specificity

Sensitivity

Highly sensitive 1–3 genome copies/PCR detection

Assay sensitivity is critical to meet regulatory expectations and provide results for early detection of mycoplasma contamination. The MycoSEQ assay consistently detects between 1 to 10 genome copies of mycoplasma target DNA. This highly sensitive method meets the rigorous expectations of regulatory agencies.

Positive means positive

Our proprietary Discriminatory Positive/Extraction Control gives you the confidence in your results.

  • Our positive control DNA is made with mycoplasma amplicon modified to have a melting temperature (Tm) outside the range of mycoplasma amplicons, providing an additional level of confirmation of positive test results.
  • Higher Tm allows discrimination between true mycoplasma and accidental contamination of test sample with positive control.
  • This helps enable simple extraction control spiking of test samples.
  • This can be used as a surrogate for mycoplasma DNA during method qualification.

Specificity

Detection of more than 90 bacterial species and contaminants

Equally important is specificity to demonstrate that only the target species are detected. The MycoSEQ assay provides highly sensitive detection of more than 90 Mycoplasma, Sprioplasma, and Acholeplasma species with no detection of non-related bacteria. The assay detects all species required by European Pharmacoepia <2.6.7>.
