The present invention provides a method of preparing a sample comprising one or more proteins of interest, the method comprising: providing a sample comprising a population of proteins of interest solubilised with a surfactant in a medium; exposing said sample to a mild precipitant to cause precipitation of said proteins; during or after the precipitation step, bringing said sample into contact with a matrix adapted to capture said precipitated proteins and prevent excessive aggregation of precipitated protein particles; and washing the matrix with captured precipitated proteins to remove the surfactant. A sample preparation device to carry out the same is also provided. |
