MycoProbe Mycoplasma Detection Kit Best Seller

A complete kit to detect common antibiotic-resistant cell culture contaminants

Why should I be worried about mycoplasma contamination?

Mycoplasma contamination affects up to 80% of continuous cell cultures. If undetected, mycoplasma contamination can have significant effects on the quality and reliability of your cell culture preparations.

Mycoplasma contamination:

• Induces deleterious effects on cell culture quality.
• Alters the phenotypic characteristics of host cells.
• Increases experimental variation.
• Is common in eukaryotic cell cultures.
• Is resistant to antibiotics such as penicillin and streptomycin.
• Has multiple sources (i.e. personnel, reagents, other infected cells).

Mycoplasma are difficult to detect because they:

• Are not visible using standard microscopes.
• Are small enough to pass through 0.45 mm sterilization filters.
• Do not produce changes in culture medium color, pH, or turbidit

What is the best method to determine if my cultured cells are mycoplasma-contaminated?

To provide an accurate and highly sensitive tool for routine screening of mycoplasma contamination in cultured cells, R&D Systems developed the MycoProbe Mycoplasma Detection Assay. This assay detects Mycoplasma 16S ribosomal RNA (rRNA) using a colorimetric signal amplification system with sensitivity comparable to PCR. The MycoProbe assay is not susceptible to common problems encountered with PCR-based mycoplasma detection kits.

The MycoProbe Mycoplasma Detection Assay:

• Detects the eight mycoplasma species known to cause 95% of eukaryotic cell culture contamination.
• Is highly sensitive (comparable to PCR).
• Is compatible with high-throughput screening.
• Does not generate false positives from amplicon contamination.
• Can be used for cell culture supernatants or cultured cell pellets.
• Can be used with samples from fresh or frozen cells.
• Does not require cells to be cultured in antibiotic-free media.
• Includes a synthetic DNA oligonucleotide positive control.
• Generates results in 4.5 hours.

Alternative Methods for Mycoplasma Detection

The MycoProbeTM Mycoplasma Detection Kit (Catalog # CUL001B) contains enough reagents to assay one 96-well plate for mycoplasma contamination.

The Wash Buffer supplied in this kit contains sodium azide, which may react with lead and copper plumbing to form explosive metallic azides. Flush with large volumes of water during disposal.

The Stop Solution provided with this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material.

When handling cell culture samples, appropriate precautions should be taken to prevent exposure to mycoplasma and other hazardous biological agents.
