ProteomicsDIA to inform Triple Quad Assay development
Mass spectrometry based targeted proteomics methods provide sensitive and high-throughput analysis of selected proteins. To develop a targeted bottom-up proteomics assay, peptides must be evaluated as proxies for the measurement of a protein or proteoform in a biological matrix. Candidate peptide se...

ProteomicsMetrologically traceable quantification of three apolipoprotein E isoforms in cerebrospinal fluid
Apolipoprotein E (apoE) is a 317-amino-acid long glycoprotein with three common isoforms (apoE2, apoE3, and apoE4) encoded by three apoE alleles (ε2, ε3, and ε4). These polymorphic forms arise from single amino acid substitutions with Cys and Arg interchanged at positions 112 and 158 (mature protein...

ProteomicsMag-Net: Rapid enrichment of membrane-bound particles enables high coverage quantitative analysis of the plasma proteome
Membrane-bound particles in plasma are composed of exosomes, microvesicles, and apoptotic bodies and represent ~1-2% of the total protein composition. Proteomic interrogation of this subset of plasma proteins augments the representation of tissue-specific proteins, representing a “liquid biopsy,” wh...
