Some cell lines need certain cell densities to proliferate. For those cells you can try using conditioned medium for setting up limiting dilution or culturing single cells together with feeder cells.

Yes, transfected mouse hepatocytes show albumin synthesis rates comparable to those of untransfected cells. Moreover the morphology and polarization of rat hepatocytes is not affected by Nucleofection™.

You should use the amount of DNA recommended in the optimized protocol for transient transfection. If obtaining a very high number of clones is important for your experiments, you can try increasing the amount of DNA. For further tips see our...

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...

Yes, even though this may sound odd since serum is generally known to inactivte proteases. We recommend it in this case, however, because the incubation times are quite long and the cells are stressed by the procedure. The amounts of enzymes should...

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.

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...
