Due to the nature of their production, biotherapeutics are difficult to manufacture. Growth conditions, purification protocols and formulation requirements can introduce unintended modifications into the protein structure that may affect its efficacy and safety. Imaged capillary isoelectric focusing (iCIEF) provides a critical measure of quality throughout the development and manufacturing of biotherapeutics by offering rapid, robust and high-resolution charge variant analysis.
A recent webinar from SCIEX and New Food, presented by Jianru Stahl-Zeng of SCIEX, outlined some of the capabilities of the new SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready. In particular, it highlighted the ability of the SCIEX 7500 System to accurately quantify 700 pesticide residues across 10 different food matrices at ultra-low trace levels. During the webinar, attendees posed various questions. Here, we share the top 5 of these questions, along with their answers.
As the per- and polyfluoroalkyl substances (PFAS) regulatory landscape evolves in the US and across the globe, the interest in PFAS continues to grow. Drinking water and food packaging are under particular scrutiny, and monitoring programs and requirements will continue to expand to include an increasing variety of sample types and PFAS compounds.
