2D-LC Solutions for the Analysis of Biopharmaceuticals

Biosim_eSem_icon.pngThe presentation summarizes the latest updates for the analysis of biopharmaceuticals using the Agilent 1290 Infinity II 2D-LC Solution. After a short introduction to the principle mode of operation, I will explain the latest 2D-LC modes; multiple heart-cutting and high-resolution sampling (HiRes). In the following, four case studies are presented for the analysis of intact and digested proteins samples. Two studies focus on peptide mapping using comprehensive 2D-LC for the identification of monoclonal antibody mutation sites with Q-TOF LC/MS detection, and on the characterization of antibody-drug conjugates and the assigning of drug conjugation sites. Beyond the capabilities of increasing peak capacity, the Agilent 1290 Infinity 2D-LC solution offers solutions for automated desalting before MS analysis as is demonstrated in the 2D-LC/MS characterization of charge variants using ion exchange and reversed-phase chromatography. Further, the Agilent 1290 Infinity 2D-LC solution finds implementation options in the process control of monoclonal antibodies which is shown for the 2D-LC analysis using combinations of Protein A quantification in combination with aggregation or charge variant analysis.

Separation Science, in collaboration with Agilent Technologies, has developed an eSeminar covering the analysis of biotherapeutics and biosimilars.
