Analysis and characterization of bispecific and multispecific antibodies

Are you looking to conduct analysis and characterization of your bispecific and multispecific antibodies?

Why characterize bispecific and multispecific antibodies ?

The analysis of bispecific and multispecific antibodies in a laboratory setting presents a complex challenge due to their unique structure and mechanism of action.

Unlike traditional monoclonal antibodies (mAbs), bispecific and multispecific antibodies are designed to recognize and bind to two or more different antigens, providing enhanced therapeutic versatility. Laboratory analysis of these molecules requires advanced methods to assess their structure, stability, binding efficacy, and their ability to induce specific biological responses.

This involves techniques such as mass spectrometry, chromatography, and functional assays to evaluate their biological activity.

Rigorous laboratory characterization is essential to ensure these antibodies meet quality (CQAs), safety, and efficacy criteria, especially in the context of their development for clinical applications.

Our analysis services

Structural analysis and characterization of bispecific and multispecific antibodies

  • Glycosylation profiling

  • De novo sequencing

Characterization of physicochemical properties

We provide precise data on the size, mass, and physicochemical properties of your bispecific and multispecific antibodies, essential for their development, validation, and quality control :

  • Molecular weight and size (intact mass by LC-MS and SEC-Triple detection)

  • Thermal stability (DSC)

  • Spectroscopic profiles (UV/visible absorption, FTIR)

  • Chromatographic profile (charge variants by IEX-UV / Ion Exchange chromatography)

  • Extinction coefficient (UV absorption)

Identification and characterization of impurities in biopharmaceutical products

The detection, analysis, and characterization of impurities are crucial to ensuring the safety, efficacy, and regulatory compliance of biosimilars :

  • Truncated forms (LC-MS)

  • Aggregation (SEC-Triple detection)

  • Post-translational modifications (PTMs) by LC-HRMS (Orbitrap and QTOF)

  • Various impurities (compliance with ICH Q3D, E&L, etc.)

For process-related impurities, our laboratory offers specific tests, such as the quantification of elemental impurities according to USP 233 and ICH Q3D, as well as extractables and leachables (E&L) analyses. We also analyze cell culture media (amino acids, vitamins, saccharides) to ensure the quality of biosimilar bioproduction processes.
