Why Mycoplasma testing is required

Mycoplasmas, the smallest known free living organisms, are relatively common bacterial contaminants of mammalian cell cultures. Regulatory guidance requires that all products derived from mammalian cell culture undergo mycoplasma testing. Mycoplasma detection is difficult, sometimes impossible, when using a traditional 28-day culture-based test. Regulatory agencies have expanded acceptance of nucleic acid tests, such as real-time PCR, as an alternative method to traditional Mycoplasma detection after appropriate validation and regulatory review. Over 40 major global biotechnology companies have implemented, validated, and received regulatory approval to use the MycoSEQ system as their mycoplasma lot release test.

MycoSEQ mycoplasma detection system

The MycoSEQ Mycoplasma Detection System is a real-time PCR based mycoplasma detection assay, providing sensitivity that meets or exceeds the regulatory guidance for mycoplasma detection and same-day actionable results to enable early detection of mycoplasma contamination. The MycoSEQ Mycoplasma Detection System integrates real-time PCR assays, instruments, and software with optimized PrepSEQ sample preparation reagents—delivering results in hours, not days. This enables you to test at multiple points in cell line and cell bank production and media harvest, to help increase your productivity and reduce the risk of downstream contamination.

MycoSEQ Mycoplasma Detection system for biologics lot release and in process testing

Following validation, regulatory review, and acceptance, the MycoSEQ assay can be used as a preferred same-day mycoplasma lot release test, replacing the 28-day culture-based test.

Highly sensitive detection across species with demonstrated sensitivity down 1–3 genome copies/PCR

Detection of more than 90 Mycoplasma, Acholeplasma, and Spiroplasma species, including commonly known contaminants within bioprocessing facilities with no cross reactivity with non-mycoplasma DNA

Streamlined workflow with results in less than 5 hours

The MycoSEQ Mycoplasma Detection System’s easy workflow delivers actionable results in less than 5 hours—enabling you to detect contamination quickly in process development, equipment, raw materials, harvest, helping to expedite the release of your product.

MycoSEQ Validated Workflow

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.

Sensitivity

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

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>.
