Quantitating antibiotics and insecticides in poultry is serious business. Overuse can lead to antibiotic resistance while insecticide residuals can cause harmful side effects in humans. In the United States, for example, the Federal Drug Administration (FDA), has offered up a plan to limit common antibiotics in feed, which are used to encourage growth. However, this is a voluntary plan, and as the following application note, “Quantitation of Antibiotics and Insecticides in Poultry Feed using LC-MS/MS,” points out, antibiotics have been shown to accumulate in poultry feathers, which are in turn used for nutritional elements in the feed. Therefore, as the government agency works on getting suppliers on board with the new plan, scientists are working on a testing method of their own which detects nine antibiotics and four insecticides in poultry feed including:
Perhaps you have seen this study, but just in case you missed it, we have included the full report in the Food & Beverage Compendium, which is now available for download.Download the Food & Bev Compendium >
Application Note at a Glance: To give you more insight into this application note and others like it in the compendium, consider how poultry feed contains many nutritional ingredients. Researchers had to design a method that included a hefty extraction method and clean-up efforts. As a result, they designed a single method to quantify a wide selection of antibiotics and insecticides in poultry feed using a QTRAP® 5500 for detection. Want to see how the extraction/sample prep was carried out? These experimental conditions along with separation and MS/MS detection are included within the compendium (pages 121 to 125).

In biopharmaceutical development, sequence variants (SV) are considered an inherent risk of producing complex proteins in living systems. Sequence variants are unintended changes to the amino acid sequence of a biotherapeutic and can be caused by errors in transcription or translation in the host cell, or cell culture and process conditions. Detailed analysis of SVs is important in process and product development to ensure the drug’s safety and efficacy. Even low‑level sequence variants can have significant implications for product quality, safety, and efficacy, making their accurate detection and characterization a critical requirement across development, process optimization, and regulatory submission.
CE‑SDS remains a cornerstone assay for characterizing fragmentation, aggregation, and product‑related impurities in therapeutic proteins. UV detection has been the long‑standing standard. However, it frequently struggles with baseline noise, limited sensitivity for minor fragments, and subjective integration.
At SCIEX, innovation doesn’t stop at instruments; it extends to how you interact with your LC-MS/MS or CE systems every day. That’s why we’re excited to introduce the SCIEX Now spring 2026 improvements: a set of meaningful enhancements shaped directly by your feedback.
