Quantitation of monoclonal antibodies (mAbs) in biological fluids is important during all stages of antibody drug development. First developed in the 1970s, therapeutic mAbs have both research and medicinal impact as they can be used for diagnosis and treatment of a wide variety of diseases, and have a high level of specificity.
Taking upwards of 10 years to bring a therapeutic mAb to market, discovering effective, high-throughput analysis methods is prudent for pharmaceutical companies to help bring these new therapies to market.
Although traditional immunoassays are typically used for biotherapeutic bioanalysis, more recently LC-MS is adopted because of its high selectivity, accuracy, and precision. In this technote, “Improving Sensitivity for an Immunocapture LC-MS Assay of Infliximab in Rat Plasma Using Trap-and-Elute MicroLC-MS,” researchers present results of samples prepared using a generic anti-human IgG immunocapture workflow.
In this method, researchers used the selective extraction of human IgG antibodies from rat plasma and then compared the use of High Flow LC-MS and Trap-Elute MicroLC-MS methodologies.
Discover how the trap-elute method ensures similar throughput to the conventional high-flow LC-MS workflow, while injecting the same 20 µL of sample, but offers enhanced protection of the MicroLC column and the MS from contamination, thus providing a more robust method.
The utilization of a trap-elute MicroLC-MS method provides a solution for applications where mAbs need to be quantified in small volume samples and at low concentrations.Learn more about micro-LC products can enhance your biologics bioanalysis studies >
As of summer 2016, 30 monoclonal antibodies (mAbs), had been approved for the treatment of certain cancers, autoimmune and infectious diseases, with even more in development.
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.
