SilverXpress Silver Stain Kits utilize ammonia silver chemistry and glutaraldehyde sensitization to produce a highly sensitive silver dye that enables detection Lower levels of protein than standard Coomassie or Colloidal Blue staining techniques. The transparent background enables sample identification to be seen at a glance and provides publication-quality gels.

DNA Staining
The SilverXpress kit can also be used to detect nanogram concentrations of DNA, but not with ethidium bromide. It is 5 times more sensitive than ethidium bromide and can detect 50 bp DNA down to less than 0.5 ng.
