THE ADDITION OF FAIMS INCREASES TARGETED PROTEOMICS SENSITIVITY FROM FFPE TUMOR BIOPSIES

Talk by Steve Sweet, Associate Director, Translational Medicine, AstraZeneca

We combined high-field asymmetric waveform ion mobility spectrometry (FAIMS) and parallel reaction monitoring (PRM) to increase assay sensitivity. FAIMS-PRM improved the overall signal-to-noise ratio over that from PRM and increased assay sensitivity for four (HER2, EGFR, cMET, and KRAS) of five proteins of clinical interest. We applied the FAIMS-PRM assay to single-section FFPE clinical samples and quantified basal HER2 expression in breast cancer samples classified as HER2 negative by immunohistochemistry. Furthermore, we determined the degree of FAIMS-dependent background reduction and showed that this correlated with an improved lower limit of quantitation with FAIMS.

HIGH-THROUGHPUT AND HIGH-SENSITIVITY BIOMARKER MONITORING IN BODY FLUID

Talk by Konstantinos Kalogeropoulos, Scientist at DTU

In this study, we report an assay utilizing the SureQuant internal standard triggered targeted method on a newest generation mass spectrometer coupled with an Evosep One liquid chromatography platform, which displays high sensitivity and a high throughput of 100 samples per day. We demonstrate the robustness of this method by quantifying proteins ranging six orders of magnitude in human wound fluid exudates, a biological fluid that exhibits sample complexity and composition similar to plasma.
