Mass spectrometry is an excellent protein analysis method widely used in medicine and agriculture, but it requires complicated and time-consuming sample preparation. In this study, we developed a new method for significantly reducing preparation time using an anion-exchange solid-phase extraction spin column that can be made from readily available materials. This new and reliable method does not require highly specialized lab technique and enables reproducible mass spectrometry from trace cell and tissue samples.
