Minerva Biolabs GmbH is proud to organize the 10th proficiency test for molecular mycoplasma detection methods for contamination control of cell culture materials and biologicals. This study was strong demanded by customer requests and was requested by the IRPCM Group “Cell Culture” of the International Organisation of Mycoplasmology (IOM).
The aim of the collaborative study is a survey on the quality of mycoplasma testing and long term to establish an external quality assurance programme and thus improving the reliability of NAT-based mycoplasma testing. The study will allow each individual laboratory an assessment of the accuracy and sensitivity of the tests carried out in international comparison. The study is organized on a semi-annual basis.
An identical set of samples will be shipped to all participants and independently analyzed under individual conditions. The results are evaluated statistically. All participants receive the evaluation for information about the correctness of the analysis as well as an individual certificate of success, if 4 of 5 samples were analyzed properly. The evaluation is anonymous. The data might be published in respect of relevance and interest at conferences or in print media but not for commercial use.
The mycoplasmas in the sample set will be titrated applying the culture method (CFU/ml) and using a qPCR method (GU/ml). The sample set may contain different sample matrices, concentrations and bacteria species.
1 sample set = 5 samples
The samples contain the full bacteria particles. Before shipping the samples will be inactivated gently and lyophilized.
For providing the sample material, the logistical effort, the evaluation and preparation of documentation a fee of 130 € plus the statutory VAT and delivery charge will apply.

Frequently Asked Questions (FAQ)
What does “NAT-Mycoplasma” mean?
Nucleic Acid Amplification Test
So, does NAT mean PCR?
Not necessarily but including PCR. Any technique which is based on the detection of DNA can be used.
Following the results obtained by end-user, will you supply a kind of “official certificate of external quality assurance”?
Yes. An official certificate for participation and/or results within the range will be issued.
Do you need that all participants declare what method of detection they use?
Yes, as this will give the participants a statistical overview on available test systems and their characteristics.
If I book via our local distributor, who will issue the certificate?
The distributor will receive the test samples and will forward them to the participant. The results will be transferred by the distributor to Minerva Biolabs for evaluation. The certificate will be issued by the distributor with the results supplied by Minerva. In all cases Minerva will not be aware of end customers contact information.
Does an end-user who makes colorimetric detection, or Elisa or another detection method could participate?
No, as the material is inactivated colorimetric assays cannot be used. The inactivation method will disintegrate the protein structure which will not allow proper ELISA.
You say that you will supply a comparable set of 5 samples. But in fact for each participant, the set of 5 will be different? Some of participants will have 5 vials with mycoplasma; some other could have 3 positives and 2 negatives …?
All participants will receive exactly the same material. Material from different proficiency runs will differ in formulation.
Do participants using a home brew method receive some kind of official certificate that their in house test is ok when they participate?
Yes, all participants will receive a certificate which either states “participated” or “completed successfully” if their results are within the statistical range of all other reports.
For statistical reasons the result report form will have a section to address the type of test used. Here they can check “homemade”.
Are those 5 samples enough for a costumer to compare eg 2 or 3 different methods?
Each sample will contain a lyophilized pellet which should be rehydrated with 300 µl of water. This volume should be enough for many PCR reactions even in case a DNA extraction is required.
Is it allowed to compare our in house test to a commercial test by using this sample set? Is the price the same for using the samples for this purpose?
All participants are treated the same way. All participants who like to use the samples to compare different methods are welcome to do so. Purchase of the sample set does not imply an obligation to provide a result report.
