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 a recent webinar, which is now available on-demand, Holly Lee powerful strategies to tackle complex residue testing. From boosting throughput to fine-tuning method sensitivity, Holly shared key ways to maximize performance across large pesticide panels.
Whether we are raising glasses of rosé in a vineyard in France or enjoying a lager in a casual street restaurant in China, it is likely that the last thing on many people’s minds is the chemical risks from their beverage. Unless you work in food science, then it might actually be the first thing.
As PFAS regulations tighten globally, laboratory managers are navigating a complex economic landscape. Whether operating in a commercial or non- commercial setting, the pressure to deliver accurate, defensible, and timely PFAS data is mounting. At SCIEX we understand that the right technology can turn this regulatory challenge into a strategic opportunity.
