# Glycosylation analysis laboratory

## As a biopharmaceutical manufacturer, you want to carry out a glycosylation analysis

### What is glycosylation?

Glycosylation is an essential biological process in which chains of sugars (glycans) are attached to [proteins](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/protein-analysis.md) or lipids. This post-translational modification (PTM) plays a key role in the structure, stability, and function of biomolecules. It is particularly critical in the biopharmaceutical field [biopharmaceutical](https://filab.fr/en/sectors-of-activity/biopharmaceutical.md), where it influences the efficacy and immunogenicity of [biomedicines](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-nitrosamines/laboratory-analysis-biomedicine.md), including [monoclonal antibodies (mAbs)](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/analysis-characterization-monoclonal-antibodies-mabs.md) and therapeutic proteins.

### Why perform a glycosylation analysis?

Glycosylation analysis is essential to ensure the quality and performance of biopharmaceuticals. It makes it possible to verify compliance with international regulatory requirements such as those of **EMA, FDA and ICH**. The analysis also helps **assess the stability** of biomolecules throughout development and production, thereby ensuring optimal performance.

In bioproduction, identifying and controlling **glycosylation profiles** makes it possible to optimize manufacturing processes and improve the yield of biopharmaceutical production. Finally, this analysis can detect **structural variations** that could affect the therapeutic efficacy and safety of products administered to patients.
