Systematic evaluation and optimization of protein extraction parameters in diagnostic FFPE specimens. The exact protocol described above was developed in the publication Automated sample preparation with SP3 for lowinput clinical proteomics by Mueller et al. Formalin-fixed, paraffin-embedded (FFPE) tissue sections must be treated to remove the paraffin (de-paraffinization, de-waxing) and unmask hidden or latent epitopes in preparation for immunohistochemical (IHC) staining. Deparafinization of FFPE samples is typically performed using a non-polar solvent, such as xylene, or a mineral oil-based method which can be time consuming and messy. For all deparaffinization methods, specimens were Proteinase K digested at 56C for 60 min and then demodified by . If paraffin is not removed, epitopes will not be fully exposed leaving them .
