Post-Translational Modification AnalysisOnline Inquiry
As a good partner of pharmaceutical companies and research institutions, Creative Proteomics has rich experience in protein post-translational modification (PTM). PTM can affect structure, stability, function, and the way proteins interact. Characterization of PTMs and determination of protein modification sites are important for the discovery and study of protein modification sites for elucidating the function of proteins. Creative Proteomics can provide PTM site identification, characterization, and quantitative analysis of proteins using high resolution mass spectrometry combined with bioinformatics analysis.

Methods of Post-translational Modification Analysis Services We Can Provide:
Combined with our mass spectrometry platform, we can provide you with the following two strategies for post-translational modification analysis.
This method requires the enzyme to cut the protein into peptides of a certain size. Then use HPLC or Nano-LC combined with mass spectrometry for analysis. It is a universal and commonly used method suitable for large-scale protein analysis. But this method cannot analyze the connection between different modifications. If you need to analyze the association of different modifications, you can choose Top-Down Mass Spectrometry.
This method does not require the process of enzymatic digestion, and directly analyzes intact proteins. It can provide more accurate and richer biological information for complete proteins. "Top" refers to the accurate measurement of the molecular weight of intact proteins, while "down" refers to the fragmentation of intact proteins through tandem mass spectrometry. Its sequence coverage can reach 100%. This method distinguishes between different protein variants and also provides information on the stoichiometry of all modifications.
