AdipoGen Stains-all
Chemical. CAS 7423-31-6. Formula C30H27BrN2S2. Molecular Weight 559.6. Stains-all is a carbocyanine dye, which stains anionic proteins, nucleic acids, anionic polysaccharides and other anionic molecules. Stains-all is metachromatic and changes its color dependent on its contact to other molecules. The detection limit for phosphoproteins is below 1ng after one hour of staining, for anionic polysaccharides between 10 and 500ng. Highly anionic proteins are stained blue, proteoglycans purple and anionic proteins pink. RNA is stained blueish-purple with a detection limit of 90ng and DNA is stained blue with a detection limit of 3ng. Stains-all is light sensitive, therefore the staining is performed in the absence of light and photographed immediately. Staining of proteins can be improved by a subsequent silver stain.
