Your need : to ensure the quality and conformity of your products by controlling their protein composition
Proteomics analysis
Proteomic analysis is a cutting-edge method used to identify, characterize and quantify the proteins present in complex biological samples. These studies explore the proteome, i.e. all the proteins expressed in a cell, tissue or organism at a given time.
Composition, structure and quantification of proteins
A proteomic analysis provides data on :
- Protein composition: identification of proteins of interest or undesirable proteins (e.g. contaminants or allergens).
- Protein structure: analysis of post-translational modifications, conformations or protein-protein interactions.
- Protein quantification: monitoring the concentration of active proteins or biomarkers in a product or process.
Proteomics analysis for biopharmaceuticals
Proteomic analysis is essential to guarantee the quality, safety and efficacy of biotherapies such as recombinant proteins, monoclonal antibodies and vaccines.
Recombinant proteins, used in numerous treatments, require precise characterisation to verify their structure and detect any post-translational modifications. Monoclonal antibodies, essential in targeted therapies, require in-depth analysis to ensure their purity, stability and ability to interact correctly with biological targets. Finally, vaccines, whether protein- or nucleic acid-based, require proteomic validation to guarantee their efficacy and eliminate the risks associated with contaminants or structural variations.
Proteomics can be used to characterise post-translational modifications, ensure protein integrity and meet biopharmaceutical regulatory requirements.
Proteomic analysis to control biotherapies
For biosimilars, proteomic analysis ensures equivalence with the original products. For plasma-derived products, this analysis ensures the identification and quantification of critical proteins, while optimising manufacturing processes.
Proteomic analysis thus offers solutions for securing and optimising the development and production of these biotherapies.
Why carry out a proteomics analysis in the laboratory?
Proteomics analysis enables manufacturers in the biopharmaceutical sector to meet :
- Quality control and compliance: guarantee the integrity, stability and safety of therapeutic proteins while meeting strict regulatory requirements.
- Bioprocess optimisation: characterize key proteins to improve formulations and control critical stages in the manufacturing process.
- Contaminant detection: identify exogenous or trace proteins that could compromise the purity or efficacy of biotherapies.

Analysis by MALDI-TOF and mass spectrometry
Proteomics analysis is based on advanced technologies such as mass spectrometry, and in particular the MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization – Time of Flight) method:
- Rapid, accurate identification of proteins.
- Analysis of complex samples without prior purification.
- Ability to detect contaminants or perform serial analyses.
Mass spectrometry is a key technology in proteomics analysis, enabling :
- Identification of proteins of interest or contaminants.
- Structural analysis of post-translational modifications and protein-protein interactions.
- Quantification of active proteins or biomarkers.
FAQ
Proteomics analysis is important for guaranteeing the quality, safety and efficacy of biotherapies. It is used to characterise therapeutic proteins (e.g. recombinant proteins, monoclonal antibodies) by detecting post-translational modifications, structural variations and possible degradation, in order to meet strict regulatory requirements and ensure product stability.
For biosimilars, proteomics analysis is essential to demonstrate their equivalence with reference products. It enables detailed comparison of protein profiles, identifying any differences and ensuring that biosimilars meet the same standards of quality, efficacy and safety as the original, in compliance with regulations.
In quality control, proteomics analysis is used to check the purity of batches, identify degraded or modified proteins and detect any contamination. These analyses ensure that each batch produced meets the defined specifications and avoid the risk of product rejection or recall.
Proteomics analysis can be used to optimise bioprocesses by identifying critical protein-related stages (e.g. aggregation, degradation). This helps to improve yields, reduce production costs and avoid interruptions due to quality problems. It is also essential for validating changes to manufacturing processes or raw materials.
For the cosmetics industry, proteomics analysis plays a key role in the identification and validation of biological actives, particularly bioactive peptides used in anti-ageing or moisturising formulations. Manufacturers need precise control to ensure that the biological mechanisms targeted by their products are effective, while guaranteeing the absence of contaminants or allergens in the formulations.
