Description & Advantages

Mycoplasma are small, structurally simple bacteria which lack a cell wall and represent one of the most prevalent and serious sources of cell line contamination. Mycoplasma contamination is invisible, as it causes no discernible change in turbidity or pH even at densities as high as 108 organisms/mL, making it particularly insidious. Mycoplasma infections are highly toxic and can induce a range of changes in cell cultures, including reduced growth rates, abnormal morphology, chromosomal abnormalities, and metabolic disturbances. These changes can lead to slowed cell growth, aberrant differentiation, or even cell death, severely disrupting normal cell functions. Mycoplasma contamination not only significantly affects the reliability, repeatability, and consistency of experimental results but can also lead to experimental failure. Therefore, timely and accurate detection of mycoplasma contamination is crucial for ensuring the quality of cell cultures and the accuracy of experimental outcomes.

 

MCE Mycoplasma Detection Kit (PCR) is a diagnostic kit that utilizes the PCR method to detect mycoplasma contamination in biological materials such as cultured cells. The kit includes PCR premix and specific primers targeting the conserved regions of the mycoplasma 16S rRNA gene, allowing for the specific amplification of mycoplasma DNA directly using cell culture fluid as a template, thereby enabling the detection of mycoplasma.

 

Features of MCE Mycoplasma Detection Kit (PCR)

1. High Sensitivity: Capable of detecting as low as 20 copies of mycoplasma.

2. High specificity: PCR amplifies only mycoplasma DNA, without amplifying eukaryotic or bacterial DNA.

3. Easy to Operate: No need for mycoplasma genomic DNA extraction, making it suitable for testing a large number of cell samples.

4. Fast: Detection process can be completed within 2 h.

5. Accurate: Equipped positive and negative controls to ensure the accuracy of PCR results.

Protocol

General Protocol

1. Sample preparation

1) Culture cells for 48-72 h and collect culture medium when cell density reaches approximately 80%. For suspension cells, centrifuge at low speed and use the supernatant.

2) Heat an appropriate amount of culture supernatant at 95°C for 5 min, briefly centrifuge, and use the supernatant as template. Serum may be diluted with Mycoplasma-Free Water and treated in the same manner.

2. PCR reaction system

Component Test sample Positive control Negative control
PCR Master Mix (2×) 10 μL 10 μL 10 μL
Primer Mix 0.4 μL 0.4 μL 0.4 μL
Template 1 μL test sample 1 μL Positive Control -
Mycoplasma-Free Water 8.6 μL 8.6 μL 9.6 μL
Total volume 20 μL 20 μL 20 μL

Note: Include a positive and negative control in each run. Whenever possible, prepare PCR mixtures and add templates in separate clean areas. Wear a mask and use sterile filtered tips to reduce aerosol and environmental mycoplasma contamination.

3. PCR cycling program

Step Temperature Time Cycles
Initial denaturation 94°C 3 min 1
Denaturation 94°C 15 sec 35-40
Annealing 56°C 15 sec 35-40
Extension 72°C 15 sec 35-40
Final extension 72°C 1 min 1

4. Electrophoresis and interpretation

Analyze PCR products on a 1%-1.5% agarose gel and compare with positive and negative controls. A mycoplasma-specific band at the same position as the positive control indicates a positive sample. No specific band should be present in the negative control.
