For preventive treatment of my cultures, should I use Normocin or Plasmocin ?
The choice of preventive treatment depends on the kind of contaminants you may have observed in your cell-culture facility. Each cell-culture room is a specific case. If bacteria, yeasts, and filamentous fungi are the most frequent contaminants in a given facility, Normocin is best suited. If contaminations are mostly due to mycoplasmas, plasmocin should be used instead. Note that the dominant kind of infection may change according to the calendar. For example, during winter your primary concern may be mycoplasmas (plasmocin preventive treatment), but with rinsing temperatures and hygrometry around summer the bane of yeast contaminations may overide most concerns about mycoplasma infections.
