Reversed-Phase Separation of Intact Therapeutic Antibodies Using the Vanquish Flex UHPLC System

Reversed-Phase Separation of Intact Therapeutic Antibodies Using the Vanquish Flex UHPLC System

10 Aug 2016

In this application note, the MAbPac-RP column was operated with the Vanquish Flex UHPLC system for the reversed-phase chromatography of several intact therapeutic antibodies. To assess the suitability for stability studies, the chromatograms of a reference and a stressed mAb were compared.

Thermo Scientific™ Vanquish™ Flex Quaternary UHPLC System

Thermo Fisher Scientific

The Thermo Scientific™ Vanquish™ Flex Binary UHPLC system is biocompatible with a state-of-the-art binary high-pressure pump and state-of-the-art binary solvent blending. This ultra high performance liquid chromatography system shares all Vanquish values, such as a design focused on uptime, robustness and reliability. Multiple detection options as well as Thermo Scientific™ Viper™ fingertight connections throughout the system will give you the performance you need with the ease of use you want.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Monoclonal AntibodiesMonoclonal antibodies (mAbs) are lab-made molecules that can bind to specific antigens on cells, making them highly effective in treating cancers, autoimmune diseases, and infections. These targeted therapies are transforming the treatment landscape for many conditions. Browse our peer-reviewed product directory to find monoclonal antibodies for research and clinical applications; compare products, check reviews, and get pricing directly from manufacturers.Protein SeparationBiopharmaceuticalsBiopharmaceuticals are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or for in vivo diagnostics. The most well known example of a biopharmaceutical product, and the first to be approved for therapeutic use, was recombinant human insulin.Therapeutic AntibodiesTherapeutic antibodies are antibodies engineered for use in treating diseases. They can be designed to target specific antigens, blocking harmful interactions or modulating immune responses. Therapeutic antibodies are critical in treating conditions like cancer, autoimmune disorders, and infectious diseases.
