Introducing the Supel-Select SCX SPE Tube from Sigma Aldrich

The SilverQuest™ Silver Staining Kit provides a rapid and easy method to silver stain proteins and DNA in polyacrylamide gels. Silver staining allows detection of most proteins since it is 30-fold more sensitive than staining with colloidal Coomassie® G-250. The SilverQuest™ Silver Staining Kit is specifically designed to provide sensitive silver staining compatible with mass spectrometry analysis. Ideal for rapid preparati…
