Plasmocin™ - Mycoplasma Elimination Reagent
Elimination and Prevention of Mycoplasma Contamination in Cell Cultures
Plasmocin™ is used to cure cell lines infected by mycoplasma and related cell wall-less bacteria.
Plasmocin™ can also be used as a routine addition in liquid media to prevent mycoplasma and more generally bacterial contamination in small and large animal cell cultures.

Warning: InvivoGen's anti-mycoplasma products are suitable for research purposes only, and not for human or animal care.
Treat up to 25 cell lines in T75
Plasmocin™ is provided as a yellow solution at different concentrations:
- 25 mg/ml (Plasmocin™Treatment)
- 2.5 mg/ml (Plasmocin™ Prophylactic)
In contrast to other anti-mycoplasma compounds, Plasmocin™ is active on both free mycoplasmas and intracellular forms. This advantage is conferred by one component of Plasmocin™ which is actively transported into mammalian cells. It ensures that following treatment with Plasmocin™ a cell culture is not reinfected by mycoplasmas released from intracellular compartments of infected cells.
In all animal cell lines tested to date, even at five times the working concentration, no apparent adverse effect on cellular metabolism is observed.
No resistance in liquid cultures of mycoplasmas has ever been identified in repeated experiments attempting to measure the mutation rate. Therefore, development of resistant mycoplasma strains is virtually eliminated.
Plasmocin™ is also active at low concentrations on a broad range of Gram positive and Gram negative bacteria that are otherwise resistant to the mixture of streptomycin and penicillin, and exhibits no toxicity in eukaryotic cells.
Many cell lines infected by mycoplasmas have been successfully treated with Plasmocin™, including embryonic stem cells, hybridomas and retrovirus packaging cells.
Comparison of the most common anti-mycoplasma agents[1-3]
|Product||Supplier||Treatment||Ease of use||Efficacy||Cytotoxicity||Resistance|
|Ciprobay||Bayer||12 to 20 days||+||++||+/-||+|
|MRA||ICN||1 to 2 weeks||+||++||+/-||+|
Antibiotics commonly used in cell culture are inactive on mycoplasma (e.g. penicillins and streptomycin). Three classes of antibiotics have been shown to kill mycoplasma at relatively low concentrations: tetracyclines, macrolides and quinolones. Tetracyclines and macrolides block the protein synthesis by interfering with ribosome translation, while quinolones inhibit the replication of bacterial DNA.
Several antibiotics are commercially available for the removal of mycoplasma: BM-cyclin (Roche) contains a macrolide and a tetracycline, Ciprobay (Bayer, available only with a prescription) and MRA (ICN) are both quinolones. Plasmocin™ is the only antimycoplasma reagent that combines a macrolide and a quinolone. Unlike BM-Cyclin that requires the sequential and cyclic use of 2 antibiotics, Plasmocin™ is ready-to-use and can be added to the culture medium directly. Furthermore, the 2 antibiotics in Plasmocin™ act on separate targets blocking protein synthesis and DNA replication, whereas the 2 antibiotics in BM-Cyclin are both inhibitors of protein synthesis. Therefore, Plasmocin™ is more effective in removing mycoplasma and prevents the appearance of resistant strains. In contrast to other anti-mycoplasma compounds, Plasmocin™ is active on both free mycoplasma as well as intracellular forms. This advantage is conferred by one component of Plasmocin™ which is actively transported into mammalian cells. It ensures that following treatment with Plasmocin™ a cell culture is not reinfected by mycoplasma released from intracellular compartments of infected cells. To date, no consistent and permanent alterations that affect the eukaryotic cells during and after the treatment have been detected.
