 Robust PFAS Determination in Animal Derived Foods
This application note demonstrates a rapid Blend‑and‑Inject LC‑MS/MS method using the QSight 500 system for quantifying 25 PFAS compounds in animal‑derived foods. Eliminating SPE, it simplifies sample preparation while delivering EU‑compliant sensitivity, robust accuracy, and high‑throughput performance, enabling efficient routine monitoring of PFAS in complex food matrices.

The resource maps tissue-specific protein patterns, cancer-associated changes, organ-specific drug-toxicity signals, and candidate therapeutic targets. | | | | | | |  Purdue develops next-generation platform to accelerate cancer drug discovery Researchers at the Purdue Institute for Cancer Research (PICR) have developed a next-generation technology platform designed to dramatically accelerate one of the slowest and most challenging stages of cancer drug discovery: identifying promising compounds that could eventually become new therapies. | | | | | | |  Gut bacteria may help explain why fatigue appears before illness A small study of healthy Japanese adults found that fatigue was associated with distinct gut microbiome, microbial gene, and fecal metabolite patterns. The findings suggest fatigue may track with altered microbial energy metabolism and oxidative stress-related functional potential, but larger longitudinal studies are needed to test causality and clinical value. | |
