I got this in an email today--I think you'll find it interesting:

Genlantis now provides a proven disinfection solution for cleaning up mycoplasma-contaminated cells with MycoGONE. This powerful and effective combination of antibiotics kills all known mycoplasma strains and is safe for mammalian cell culture use.

Mycoplasma contamination is a serious threat to cell culture based laboratory research. Studies have found as many as 85% of cell cultures tested show signs of contamination. This is not surprising considering the multiple sources of contamination, such as serum, media, additives, laboratory personnel, and faulty equipment (tissue culture hoods or incubator chambers). Mycoplasma's negative impact tends to go unchecked due to the difficulty in detecting these ubiquitous bacteria. Widespread Mycoplasma contamination in a cell culture laboratory can lead to costly and time-consuming clean-up procedures Thus, it is highly recommended to perform regular screenings, and proven disinfection methods if mycoplasma contamination is found.
