Confident protein characterization methods

Get the latest information on the analysis of biotherapeutic proteins such as monoclonal antibodies (mAbs) in their intact form. UHPLC is ideal for identifying modifications such as charge variants, as well as higher order structures through aggregation. Use our broad range of leading column chemistries for these and other intact analyses by liquid chromatography (LC). For rapid and precise accurate mass determination, try our uniquely powerful Thermo Scientific Orbitrap-based mass spectrometers (MS) for analysis of both denatured and native intact proteins.

Featured software for intact protein analysis workflows

Powerful, yet simple protein deconvolution and peptide mapping software

Screen, identify, and characterize intact proteins with higher productivity and confidence using the Intact Protein workflow in BioPharma Finder software. Two deconvolution algorithms take full advantage of the high-quality HRAM data produced by Orbitrap mass spectrometers. In addition to intact characterization, you can confirm amino acid sequence, identify site and type of known/unknown post translational modifications, while providing relative amounts using Peptide Mapping workflows. Additional features include disulfide linkage, sequence variant analysis, and sequence alterations.


Intact protein analysis under native mass spectrometry conditions preserves structurally-critical non-covalent binding between antibody chains. Providing the ideal technique to aid characterization of antibody drug conjugates (ADCs) and other heterogeneous antibody samples. Find out more about our routine native analysis columns and on-line size exclusion chromatography (SEC).

Determination of protein concentration, known as titer, is widely used in the biotechnological protein production process. Choose from our wide range of affinity columns and resins from discovery to QA/QC for titer measurement. Our range of protein-A protein purification columns can automate biopharmaceutical protein isolation ahead of additional characterization steps, such as charge variant profiling.
