SWATH® Acquisition: On the Forefront of HIV-1 Research
World AIDS Day is held on the 1st December each year and is an opportunity for people worldwide to unite in the fight against HIV, show their support for people living with HIV, and to commemorate people who have died. World AIDS Day was the first ever global health day, held for the first time in 1988.

A research team at the University of Nebraska Medical Center (UNMC) is using SWATH Acquisition to advance a host-oriented antiviral strategy that targets the biomolecules required for viral replication.
Using SWATH for quantitative proteomics together with bioinformatic analyses to identify host proteins, the team quantified the expression of 3,608 proteins in uninfected and HIV-1-infected monocyte-derived microphages.
Of these, they found that 420 were significantly altered upon HIV-1 infection, and the findings highlighted a novel set of proteins and processes that are involved in the host response to HIV-1 infection.

In this informative presentation, you’ll learn:
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.
