Mycoplasma test kit for fast and reliable detection in cell culture

Mycoplasma contamination is one of the most common hidden threats in cell culture, making the use of a reliable mycoplasma test kit essential for early detection and routine laboratory quality control.

AnyGenes® provides MycoDiag®, a qPCR and PCR mycoplasma test kit designed for fast, sensitive and reliable detection of mycoplasma contamination directly from cell culture supernatants.

qPCR / PCR Results < 2 hours Cell culture supernatants 25 common species

Less than 2 hours Fast mycoplasma detection for routine cell culture screening.

Why is mycoplasma contamination a major problem?

Mycoplasma are small bacteria without a cell wall that can contaminate cell cultures without obvious visible signs.

In contaminated cultures, mycoplasma can affect several biological and experimental parameters, including:

  • altered gene expression
  • reduced cell growth
  • failed or inconsistent transfections
  • changes in metabolism
  • modified cell morphology or phenotype
  • unreliable qPCR, RNA-seq, or biomarker analysis results

As a result, undetected contamination can lead to false or misleading experimental conclusions, especially in studies focused on gene expression, signaling pathways, inflammatory responses, RNA-seq validation, and biomarker discovery.

Routine testing with a sensitive mycoplasma detection kit is therefore essential to help maintain reliable and reproducible cell culture experiments.

How does a mycoplasma test kit detect contamination in cell culture?

PCR-based methods are widely used to detect mycoplasma contamination in cell culture.

The AnyGenes® MycoDiag mycoplasma test kit enables direct detection of Mycoplasma DNA from cell culture supernatants using Real-Time qPCR or EndPoint PCR.

MycoDiag is designed for laboratories that need a fast, sensitive, and easy-to-use solution for routine mycoplasma screening.

Key features include:

  • direct detection from cell culture supernatants
  • results available in less than 2 hours
  • compatibility with Real-Time qPCR and EndPoint PCR workflows
  • high sensitivity and specificity
  • reproducible performance across standard PCR/qPCR platforms
  • built-in controls to help avoid false-negative results

Why use a qPCR mycoplasma test kit?

qPCR is a fast, sensitive, and reproducible method for detecting mycoplasma contamination in cell culture samples.

Compared with slower or less direct approaches, a qPCR mycoplasma test kit offers several advantages for routine laboratory screening:

  • rapid turnaround time
  • detection of low-level contamination
  • direct analysis from cell culture supernatants
  • broad detection coverage
  • reproducible results
  • suitability for routine quality control workflows

This makes qPCR-based solutions such as the MycoDiag mycoplasma test kit particularly useful before critical experiments, including qPCR analysis, RNA-seq, transfection assays, cell-based assays, and biomarker studies.

Built-in controls for reliable results

Each MycoDiag® kit includes a complete control system to support reliable interpretation of results.

Positive control Mycoplasma DNA

Used to validate amplification and confirm assay performance.

Negative control No-template control

Used to monitor potential contamination during the PCR/qPCR workflow.

Internal control PCR inhibition check

Used to detect PCR inhibitors and help avoid false-negative results.

Why it matters: this internal quality control system is particularly important for routine testing, where sample quality and PCR inhibition can affect result interpretation.

Visual confirmation with end-point PCR

For end-point PCR applications, agarose gel electrophoresis allows visual confirmation of amplification.

In case of mycoplasma contamination, bands between 121 and 230 bp can be observed after PCR amplification with the MycoDiag® mycoplasma test kit.

When should you use a mycoplasma test kit?

Regular mycoplasma testing is essential to maintain reliable cell culture experiments.

It is recommended to test cell cultures:

  • before starting critical experiments
  • before RNA-seq analysis
  • before qPCR or gene expression analysis
  • before transfection experiments
  • after thawing cells
  • when introducing a new cell line into the laboratory
  • when cells show unexpected growth or phenotypic changes
  • every 1 to 2 weeks in routine culture workflows

Using a routine mycoplasma test kit helps laboratories detect contamination early and reduce the risk of losing valuable samples, time, and experimental data.

Use a mycoplasma test kit to protect gene expression data

Mycoplasma contamination can significantly affect biological results.

For laboratories working on gene expression, qPCR, RNA-seq, signaling pathways, inflammation, metabolism, or biomarker discovery, contamination can introduce bias and lead to incorrect biological interpretation.

Using a reliable mycoplasma test kit such as MycoDiag helps researchers:

  • protect experimental reproducibility
  • prevent data bias
  • maintain reliable cell culture conditions
  • secure long-term research projects
  • reduce the risk of false conclusions in gene expression studies
  • support quality control before qPCR, RNA-seq, or biomarker analysis

This makes mycoplasma screening a critical step in molecular biology and cell culture workflows.
