Filter aided sample preparation (FASP) This protocol describes a procedure for proteomics sample prep using medium to high amount of starting material (1-50 µg, indicatively). It utilizes membrane filter cartridges to perform all steps and yield a high quality peptide mixture from a variety of sample types. The protocol describes the procedure for formalin fixed paraffin embedded tissue samples, but it can be adapted to any type of protein sample. This method is compatible with detergents and other chemicals that are not normally recommended for MS analysis.

In-gel digestion This protocol is intended for protein ID experiments, and it is a good standard procedure for most in-gel digestion experiments.

Advanced in-gel digestion This page was created by the University of Washington Proteomics Resource (UWPR) and contains protocols for both standard as well as quantitative in-gel digestion sample preparation. In addition, it contains a list of useful staining kits compatible with mass spectrometry, as well as other resources to optimize in-gel digestion.

Single-Tube Solid Phase-enhanced Sample Preparation (SP3) This protocol utilizes magnetic microparticles that have been functionalized with COOH moieties. The microparticles can capture proteins (and anything with a primary amine group), and the magnetic property allows to separate the solvent (and the chemicals/contaminants) from the protein during the sample preparation. It can handle very low protein amounts down to few ng.  This method is compatible with detergents and other chemicals that are not normally recommended for MS analysis.
