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.
The Echo® MS+ system is a novel platform for Acoustic Ejection Mass Spectrometry (AEMS) and combines the speed of acoustic sampling with the selectivity of mass spectrometry. This platform has been designed for high throughput analysis of small and large molecules. The technology combines Acoustic Droplet Ejection (ADE), an Open Port Interface (OPI) and could be coupled with the SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system.
The Echo® MS+ system comprises of an open-port interface (OPI) and acoustic droplet ejection (ADE) module which could be coupled with a mass spectrometer. The mass spectrometer could either be a SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system. This non-liquid chromatography based; high-throughput screening platform enables rapid analysis of compounds at speeds of up to 1 sample/second.
The ability to consistently achieve reproducible results on many complex samples across multiple days is critical to a routine clinical laboratory. Laboratories relying on analytical instrumentation require stability and robustness to perform a variety of screening and confirmatory assays with confidence. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the preferred analytical method in the clinical laboratory to reliably perform clinical testing as it provides best-in-class performance and reliability for the most challenging assays. LC-MS/MS offers the required levels of sensitivity and specificity for the detection and quantitation of molecules from complex biological samples, helping laboratories deliver highly accurate data for a variety of clinically relevant analytes across a wide range of assays.
