Protein Discovery introduced this week PPS Silent Surfactant, an acid-cleavable detergent for cell membrane disruption and protein solubilization. According to the company, the new reagent offers the same detergent properties as conventional surfactants, but when it is no longer needed, it degrades into easily removed compounds with no detergent activity, instead of retaining foaming and other detergent properties that interfere with the final stages of mass spectrometry sample preparation.
