A system, kit and process for the separation, recovery, purification and identification of biomarkers such as peptides and the like from serum or plasma. The process is to filter the sample through a UF filtration device optionally having a vertical or substantial vertical ultrafilter membrane, especially when in a single well configuration device. The filtrate is recovered and if desired desalted using various chromatography media such as reverse phase and ion exchange media. The sample is then applied to a MALDI/TOF target or HPLC column and analyzed in a mass spectrometer the presence, absence or variation of the biomarkers. Higher recovery and concentration of these biomarkers is achieved with the present invention.
