The Thermo Scientific Vanquish Flex UHPLC system with UV detection is applied for the charge variants analysis of NISTmAb Humanized IgG1K monoclonal antibody using strong cation exchange-based chromatographic separation on a MAbPac SCX-10 column. The use of Thermo Scientific CX-1 pH gradient buffers enabled high resolution separation of reference material monoclonal antibody charge variants using a 30 minute gradient.

The Thermo Scientific MAbPac SCX-10 column is applied to the charge variant analysis of Cetuximab. Ion exchange separation was performed using a pH gradient on a Thermo Scientific Vanquish Flex UHPLC system with UV detection at 280 nm. Use of Thermo Scientific CX-1 pH gradient buffers enabled high resolution separation of monoclonal antibody charge variants over a 30 minute gradient.

The Thermo Scientific MAbPac SCX-10 column is applied for charge variant analysis of Infliximab. Ion exchange separation was performed on a Vanquish Flex UHPLC system using a pH gradient and UV detection at 280 nm. Use of Thermo Scientific CX-1 pH gradient buffers enabled high resolution separation of monoclonal antibody charge variants over a 30 minute gradient.

Ion exchange separation is applied for charge variant analysis of Bevacizumab using a pH gradient on a Thermo Scientific MAbPac SCX-10 column. The Thermo Scientific Vanquish Flex UHPLC system with UV detection at 280 nm was used with Thermo Scientific CX-1 pH gradient buffers enabled high resolution separation of monoclonal antibody charge variants over a 30 minute gradient.

The Thermo Scientific Dionex UltiMate 3000 LC Bio-LC system is applied for the Ion Exchange analysis of Denosumab. The separation was performed on a Thermo Scientific MAbPac SCX-10 and pH gradient buffers with a UV detection at 280 nm. With a run time of 50 minutes the method allows easy separation of charge variants of Denosumab.
