The contamination of cells with mycoplasma is a very common problem, even though it often goes unnoticed since no cloudiness appears in the cell culture. Nevertheless the contamination often causes biochemical changes as well as changes in the immunological properties of the cells. Therefore Tico Europe offers two different products: Pharmacidal, for disinfecting surfaces in CO2 incubators and Aquaguard-1 for disinfecting water baths in CO2 incubators.
