Introduction Low sensitivity methods in protein LC–MS bioanalysis commonly utilise a ‘bottom-up’ approach. However, lack…
In this application note, Yun Alelyunas (Waters Corporation) describes an LC-HRMS method for high sensitivity bioanalysis of monoclonal antibodies by direct mass measurement at the intact level for whole molecule quantification. This emerging approach can serve as an alternative or complement to traditional methods such as ligand binding assay for protein quantification. Methodology and guidance for evaluating and optimizing data processing parameters are discussed in detail.
Waters’ team of bioanalysis experts developed the Peptide & Protein Bioanalysis Boot Camp – a…
