Can PPS Silent Surfactant be stored after it has been re-suspended?
PPS can be stored if resuspended in an aprotic solvent such as DMSO. Our recommendation would be to make a stock solution of 20x PPS in DMSO, aliquot and freeze for use later. It is important to be sure that the DMSO used in dry. If contaminated with water, the PPS will hydrolyze even in the DMSO stock. Once resuspended in protic solvent (e.g. water or buffer) the PPS should be used within the day.
