Elimination and prevention of mycoplasma contamination in cell cultures

Plasmocin™ is a broad-spectrum anti-mycoplasma and related cell wall-less bacteria reagent.

InvivoGen offers Plasmocin™ prophylactic and Plasmocin™ treatment.
Plasmocin™ prophylactic can be used as a routine addition in liquid media to prevent mycoplasma and more generally bacterial contamination in mammalian cell cultures.
Plasmocin™ treatment can effectively cure mycoplasma contamination within two weeks, without affecting cell stemness, pluripotency nor viability [1].

Plasmocin™ contains two bactericidal components:
- the first component acts on the protein synthesis machinery by interfering with ribosome translation
- the second component acts on DNA replication.

Plasmocin™ is active on both extracellular and intracellular mycoplasmas. It is 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 towards eukaryotic cells.

Many cell lines infected by mycoplasmas have been successfully treated with Plasmocin™ [2], including primary cancer cell lines [3], virus producing cells [4] and induced pluripotent stem cells [5], without inducing any permanent alterations.
