For decades, SCIEX has been part of bioanalytical innovation, empowering scientists in pharma and biopharma to push the boundaries of sensitivity, accuracy, and throughput. Across complex workflows and increasingly challenging therapeutic modalities.
Today, we’re spotlighting three peer‑reviewed publications, spanning nearly thirty years, that reflect how the scientific community continues to innovate. From oligonucleotide quantitation to protein bioanalysis, these studies highlight the evolution in the field and the long-term partnerships we value.

The study showcased how thoughtful chromatographic design, structured optimization, and careful attention to matrix effects could deliver reliable quantitation even in challenging biological samples. Many of the best practices introduced here, including instrument stability, ionization efficiency, and systematic validation, still underpin quantitative workflows today.
Abstract
Electrospray ionization (ESI) liquid chromatography−tandem mass spectrometry (LC/MS/MS) assays provide high-throughput and selective methods for quantitation of small molecules. Use of LC/MS/MS assays for macromolecules, like oligonucleotides, is challenging due to lack of sensitivity and low analyte recovery from biomatrixes. Due to this fact, the method of choice for oligonucleotides quantitation remains hybridization-based ligand-binding assays…

This publication introduced an innovative, cost-effective approach for protein depletion using combinations of organic solvents and acids, validated through signature peptide monitoring. The result? Cleaner extracts, improved sensitivity, and greater confidence in LC–MS/MS quantitation of therapeutic proteins.
We have developed an innovative method to remove albumin from plasma/serum samples for the LC-MS/MS quantitation of therapeutic proteins. Different combinations of organic solvents and acids were screened for their ability to remove albumin from plasma and serum samples. Removal efficiency was monitored by two signature peptides (QTALVELVK and LVNEVTEFAK) from albumin …

This 2024 publication captures the cutting edge: hybridization‑based LC–MS/MS approach to measure trace levels of free antisense oligonucleotide payload in complex biological matrices. It demonstrates how advanced workflows, combining sample prep with sensitive mass spectrometry, are enabling scientists to tackle the challenges of next‑generation modalities.
We have developed an innovative method to remove albumin from plasma/serum samples for the LC-MS/MS quantitation of therapeutic proteins. Different combinations of organic solvents and acids were screened for their ability to remove albumin from plasma and serum samples. Removal efficiency was monitored by two signature peptides (QTALVELVK and LVNEVTEFAK) from albumin. Isopropanol with 1.0% trichloroacetic acid was found to be the most effective combination to remove albumin while retaining the protein of interest. Our approach was compared with a commercial albumin depletion kit on both efficiency of albumin removal and recovery of target proteins…
Each decade has brought new questions and new scientific ingenuity to the forefront. And through it all, SCIEX solutions and partnerships have helped researchers stay ahead of the curve.
As therapeutic innovation accelerates, bioanalysis will continue to evolve. Modalities will diversify. Performance expectations will rise. Workflows will become more hybrid, more integrated, and more data‑driven. SCIEX is committed to supporting scientists on that journey with tools designed not just for today’s challenges, but for tomorrow’s discoveries.

Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
PFAS analysis is complex, but expert guidance doesn’t have to be. In this episode of our ‘Ask the PFAS expert series’, we’re joined by Michael Scherer, Application Lead for Food and Environmental, to answer the most pressing questions in PFAS analysis. From why LC-MS/MS systems are the gold standard for analyzing diverse PFAS compounds, to which EU methods deliver reliable results for drinking water, and to practical steps to prevent contamination, Michael shares actionable insights to help laboratories achieve accuracy, consistency, and confidence in their workflows.
During an LC-MS/MS experiment, traditional fragmentation techniques like collision-induced dissociation (CID) have long been the gold standard. Electron-activated dissociation (EAD) is emerging as a transformative tool that enhances structural elucidation, particularly for complex or labile metabolites.
