LC-MS analysis has become a highly useful technique for the identification, characterization and quantification of intact proteins as well as characterization of protein clippings and impurities. This technical note shows how the X500B QTOF system can be used to detect impurity levels in an intact monoclonal antibody analysis down to 0.001 ug/ul for glycosylated impurities and 0.0001 ug/ul for non-glycosylated impurities.

Presented is a three-column workflow developed for the production of a highly pure, histidine-tagged recombinant protein. A macroporous Ni2+ -charged affinity chromatography resin provides efficient capture of the target molecules with excellent selectivity, binding capacity, and recovery. This robust purification process provides the product quality, productivity, and economics demanded by today’s downstream manufacturing.

Peptide-based mass spectrometry methods are generally preferred for the site-specific quantitation of oxidation levels of biotherapeutics. In this study, differential levels of oxidation were induced by incubating a monoclonal antibody standard with increasing concentrations of oxidizing agent (H2O2) prior to digestion. The high-quality data obtained from the X500B instrument, in combination with BioPharmaView™ software, allowed accurate and automated quantitation of sites susceptible to oxidation, making it a robust tool for routine sequence coverage analysis, as well as quantitation of critical quality attributes.

Super Refining effectively removes or reduces polar and oxidative impurities, namely: moisture; residual catalyst; peroxide and aldehydes. The process does not alter the chemical structure of the excipient in any way. The removal of these impurities provides a range of added value to the formulator including enhanced API stability, improved oxidative stability, reduced cellular irritation, enhanced skin permeation and reduced taste impact.
