GNPS - SiTrap versus STrap comparison

These are supporting RAW files for the 'Detergent-free simultaneous sample preparation method for proteomics and metabolomics' SiTrap method manuscript. MDA-MB-231 cells were processed either by SiTrap methodology using SiTrap cellulose tips and two different extraction solutions or by STrap method using STrap quartz tips and SDS for extraction. 30 ug of protein was digested with trypsin in six replicates in each case. The peptides were eluted from the tips and concentrated for proteomics analysis.
