Detection of post-translational modifications (PTMS) Modifications occurring after protein translation, such as glycosylation or oxidation, can be identified. Assessment of purity and integrity Peptide mapping makes it possible to verify protein integrity and detect unwanted fragments or degradation. Quality control This technique is essential to ensure the quality of biopharmaceutical products before they are brought to market, guaranteeing that the protein structure is correct and compliant with regulatory requirements. ### Which industrial sectors use peptides? Peptides are versatile molecules used in various sectors such as pharmaceuticals and cosmetics... Their specificity and effectiveness allow them to play a key role in the development of new treatments or the improvement of skin care. This diversity of applications highlights the considerable potential of peptides and the importance of continuing research in this field. ## Our technical resources [Mass spectrometry](https://filab.fr/en/our-technical-resources/laboratory-analysis-mass-spectrometry.md) [HS-GC/MS](https://filab.fr/en/our-technical-resources/hs-gc-ms-analysis-in-the-laboratory.md) [Liquid Chromatography HPLC-MS](https://filab.fr/nos-moyens-techniques/laboratoire-analysis-chromatographie-liquide-hplc/laboratoire-analysis-hplc-ms/)and HPLC-MS/MS ([Orbitrap](https://filab.fr/en/our-technical-resources/lc-orbitrap-analysis.md)) [MALDI-TOF](https://filab.fr/en/our-technical-resources/maldi-tof-laboratory-analysis.md) [LC-QTOF-MS](https://filab.fr/en/our-technical-resources/laboratory-for-lc-qtof-analysis.md) ## Our biopharmaceutical services [Protein analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/protein-analysis.md) [Peptide analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/peptide-analysis-biopharmaceutical-services.md) [Lipid formulation analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/analysis-lipid-formulations.md) [Characterization of cell and gene therapy products](https://filab.fr/en/sectors-of-activity/biopharmaceutical/characterisation-of-cell-and-gene-therapy-products.md) [Peptide aggregate analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/peptide-aggregation-analysis-laboratory.md) [Biosimilar analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/analysis-characterization-biosimilars.md) [Lipidomic analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/lipidomic-analysis.md) [Enzyme analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/enzyme-analysis.md) [Proteomic analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/laboratory-proteomic-analysis.md) [Characterization of biotherapeutic products and recombinant proteins](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization.md) [n-glycan analysis](https://filab.fr/en/sectors-of-activity/biopharmaceutical/n-glycans-analysis.md) [Intact mass analysis ](https://filab.fr/en/sectors-of-activity/biopharmaceutical/intact-mass-analysis-laboratory.md) [De novo sequencing](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/de-novo-protein-sequencing.md) ## Our FAQ What is a peptide? A peptide is a [polymer](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory.md) of amino acids linked together by peptide bonds. There is a wide variety of peptides. A peptide can be considered a small protein, or rather a segment of a protein, since proteins are made up of one or more long peptide chains. The main distinction between a peptide and a protein lies in their size. FILAB carries out peptide analysis. Why analyze peptides? Peptide analysis is essential for several reasons: - Identification and quantification in complex samples. - Determination of amino acid sequence. - Studies of post-translational modifications. - Quality control of pharmaceutical and cosmetic products. What are the steps in a peptide analysis? The peptide analysis process includes several steps: - Sample preparation. - Separation of peptides by HPLC. - Identification and quantification by mass spectrometry. - Data analysis and interpretation of results. What are the benefits of having my peptides analyzed at FILAB? By choosing FILAB, you benefit from: - Recognized expertise in the field of chemical and biological analysis. - Cutting-edge techniques for accurate and reliable results. - Expert interpretation of results for solutions tailored to your needs. What is peptide mapping? **Peptide mapping**, or **peptide mapping**, is an analytical technique used primarily for protein characterization, particularly in the development of biopharmaceutical products. This method involves fragmenting a protein into several smaller peptides through enzymatic digestion. Once fragmented, these peptides are separated and analyzed using techniques such as liquid chromatography coupled with mass spectrometry (LC-MS)
