What are mycoplasmas?

Mycoplasmas belong to the family Mollicutes, which includes Acholeplasma, Ureaplasma and other species.However the term "Mycoplasma" is most often used as a "cover-all".More than 180 species have been identified of which 20 distinct Mycoplasma...


How often do mycoplasma contaminations occur in cell cultures?

A conservative estimate states that between 15-35% of all continuous cell cultures are contaminated with mycoplasma (Drexler HG, Uphof CC; 2002), some estimates are even higher (up to 80 % in some countries (Koshimizu K, Kotani H; 1981).


Can I use SDS as a detergent for a positive control if I do cytotoxicity assay with ToxiLight?

No. SDS has a negative influence on Adenylate Kinase (AK) activity. SDS is a cationic detergent, it is a very powerful protein denaturing agent, you will be aware of its use in SDS-PAGE for those reasons. ToxiLight™ works by measuring the activity of...


Which luminometer is suited for performing the MycoAlert® Assay?

For performing the MycoAlert® Assay in theory every luminometer is suitable as long as a specific sensitivity is given. Please find attached our list with luminometers we know to be suited to run the MycoAlert® and MycoAlert® Plus Mycoplasma...

Are there any contaminating glial cells in your Clonetics rat or mouse embryonic neuronal cells?

There will be a small amount of glial cells in the culture, these are not considered a contaminating cell type. The glial cells are necessary to help the neurons form their axons and dendrites, synchronize the activity of the axons, and remove...

What microtiter plates would you recommend for running a MycoAlert® and MycoAlert® Plus Assay on a plate luminometer?

We would recommend either Porvair Sciences 204003 or Corning Costar 3912 plates to use with the MycoAlert® and MycoAlert® Plus Assay. Both of these are solid white 96-well plates and give low background and optimal results when used with the...
