Simultaneous Determination of Molecular Size, Concentration, and Impurity Composition of Biotherapeutics with SEC and the Biopharmaceutical Platform Solution with UNIFI

27 Jul 2014

The objective of this application note is to demonstrate the ability to determine molecular weight and amount of the constituents of an antibody sample using UNIFI informatics. A purified antibody from human serum was used as a model protein to test the application.

ACQUITY UPLC BEH Columns

Waters

In 2004, Waters revolutionized liquid chromatography with the introduction of the ACQUITY UPLC System. At the heart of the system was Waters second generation hybrid, the Ethylene Bridged Hybrid (BEH) particle. In 2005, BEH Technology preparative particle sizes (2.5, 3.5, 5 and 10 μm) with the introduction of XBridge between HPLC and UPLC Technology platforms. BEH Technology particles offer: Excellent peak shape and efficiency for basic analytes A rational array of chromatographic selectivity Improvements in chemical stability at mobile phase extremes, particularly at elevated pH

Biopharmaceutical Platform Solution with UNIFI

Waters

The Waters Biopharmaceutical Platform Solution with UNIFI® integrates robust UPLC®/MS characterization technology with the UNIFI Scientific Information System for applications in bioseparations, intact protein mass analysis, peptide mapping and released glycan analysis.This platform unites all aspects of biotherapeutic analyses and workflows, enabling organizations to apply high resolution analytics across the development process continuum. The platform captures complex mass spectrometry and chromatography data, and enables laboratories to comprehensively and routinely acquire, process, and share LC and MS characterization information throughout a biotherapeutic’s lifecycle. Results can be shared from discovery to development to GxP quality control.
