NO - the lysis reagent in the MycoAlert® Assay is not strong enough to lyse bacteria / yeast. Also, the enzymes utilized are not very common in bacteria or yeast – but are universal among the mollicute family. Bacterial contamination is...

There is evidence to suggest that mycoplasma can survive in the absence of cells, some may even proliferate, but as a rule they are much more viable if cells are present.

One reason could be that your gene product is toxic to the cells. We recommend testing the construct for expression of the gene of interest by transient Nucleofection® of your cells. If the proportion of expressing cells drops between 4 and 48 hours...

As the stability and half-life of various mRNAs and their protein products varies, it is important to empirically determine the best time points for assessing target knockdown. For example, it has been documented that in mammalian cells, mRNA...

Depending on individual cell type and doubling rate, selection of stable transfectants will take between 7 and 28 days. Expansion and characterization of single cell clones will take several weeks in addition.

Yes. As the same protocol applies for any nucleic acid substrate (vectors or oligonucleotides) you can easily perform co-transfections either for transfection control or rescue experiments.

This is the normal pattern you should expect to see. Only a small proportion (1/10,000 to 1/100) of all transfected cells will integrate the transfected DNA into their genome and become stable transfectants. The remaining cells lose the transfected...

The standard protocol calls for taking 2 ml of culture media, spinning down any cells and removing 100 µl of supernatant as sample.Smaller initial aliquots of media may be taken to start with if necessary.

The most commonly used marker is the neomycin phosphotransferase (neo) gene that confers resistance to G418 to eukaryotic cells. Other markers are Puromycin, Hygromycin, Zeocin, or the HPRT gene that can be used in HPRT-deficient cells.
