Dionex NA - Measurement of siRNA Cell-Penetrating Peptides

In episode #37 of Analytically Speaking, podcast host Dr. Jerry Workman speaks with Dr. Austin Daniels, application scientist for Yokogawa Fluid Imaging Technologies, about flow imaging microscopy (FIM), a new technology for sub-visible particle characterization in biologics.

Researchers tested immobilized metal affinity chromatography’s potential for broad applications.

A recent study conducted by the University of Amsterdam (Amsterdam, Netherlands) and the University of Queensland (Queensland, Australia) developed a novel prioritization strategy that directly links fragmentation and chromatographic data to aquatic toxicity categories, bypassing the need for identification of individual compounds. LCGC International spoke to Viktoriia Turkina of the University of Amsterdam, lead author of the paper that resulted from this study, about their work.

A joint study between Selçuk University (Konya, Turkey) and Hitit University (Corum, Turkey) determined the natural occurrence and concentrations of the mycotoxins ochratoxin A (OTA) and deoxynivalenol (DON) in commercially available tortillas in Turkey. Contamination levels were quantified using validated analytical methods based on high-performance liquid chromatography (HPLC) coupled with fluorescence or ultraviolet detectors (HPLC-FLD or HPLC–UV).
