Mass Spec Protein Assays in FFPE Tissue

Liquid Tissue®-SRM assays are based on Expression Pathology’s proprietary sample processing technologies and Selected Reaction Monitoring, a quantitative mass spectrometry technique. The assays are used to measure protein expression in standard formalin-fixed paraffin-embedded (FFPE) patient tissue samples from tissue blocks or needle biopsies. 

Liquid Tissue processing makes it possible to analyze new or archival FFPE tissue samples for retrospective or prospective studies.
