# Analysis and characterization of nanobodies in a laboratory

## Are you considering analyzing and characterizing your nanobodies ?

### Why perform a nanobody analysis ?

Analyzing and characterizing nanobodies in the laboratory, which are antibodies derived from camels and llamas, is essential for evaluating their critical quality attributes (CQAs). These attributes include the primary structure, post-translational modifications, stability, and bioactivity of the nanobodies. Due to their unique small size, nanobodies exhibit distinct properties compared to traditional monoclonal antibodies, requiring specific methods for comprehensive evaluation. It is crucial to monitor these aspects rigorously throughout development and manufacturing, in compliance with guidelines such as [ICH Q6B](https://www.ema.europa.eu/en/ich-q6b-specifications-test-procedures-acceptance-criteria-biotechnological-biological-products-scientific-guideline). Understanding variations that can affect critical quality attributes  (CQAs), such as glycosylation profiles, charge variants, aggregates, or fragments, is vital for accurately assessing the heterogeneity and effectiveness of nanobodies.

### Other services: analysis of various impurities (compliance with ich q3d, e&l, etc.)

For process-related impurities, we offer specific tests such as quantification of [elemental impurities according to USP 233](https://filab.fr/en/our-services/our-analysis-services/analysis-ich-q3d-context.md) and [ICH Q3D,](https://filab.fr/en/our-services/our-analysis-services/analysis-ich-q3d-context/elemental-impurity-analysis-according-ich-q3d-laboratory.md) as well as analyses of [extractables and leachables (E&L)](https://filab.fr/en/our-services/our-expertise-services/laboratory-extractable-leachable-testing/extractable-leachable-analysis.md). We also analyze cell culture media (amino acids, vitamins, saccharides) to ensure the quality of bioproduction processes.
