Reliable and Comprehensive PTM Analysis

Post-translational modifications (PTMs) add a layer of complexity to the proteome by adding biochemical moieties to specific residues of proteins. To date, more than 600 types of PTMs have been identified. They are crucial for the normal functioning of the cells, and each modification has multiple effects on the proteins, involving their structure, function, and localization. PTMs also play key roles in a wide range of biological regulatory mechanisms, such as signaling pathways, protein-protein interactions, DNA damage response, and metabolic pathways.

Proteomics Analysis of Post-Translational Modifications

Mass spectrometry (MS)-based methods are currently the gold standard and most informative technique for the analysis of proteins and their PTM. Based on effective protein/peptide enrichment strategies, advanced MS instrumentation, and proteomics technologies, Creative Proteomics can help our global customers to perform fast and reliable deep protein PTM profiling.

Protein Post-Translational Modification Analysis Strategies

Our PTM proteomics analysis platform has a team of experts and state-of-the-art equipment to help you navigate successful research projects through strong workflow, robust analysis, and tailored services.

MS-Based Proteomics

MS-based proteomics is the method of choice for studying proteins and their PTMs. This sensitive technique allows not only the identification of previously unknown modification patterns but also the simultaneous determination of multiple isoforms of one protein with different modifications. To achieve a qualitative and quantitative analysis of various PTM, we mainly use MS-based proteomics methods, including bottom-up, middle-down, and top-down proteomics.

Functional Overview of PTMs

PTMs have been shown to have a range of cellular functions, and each modification has multiple effects on protein structure and function involving protein signaling, activity, stability, metabolism, and localization. PTMs also play key roles in a wide range of biological regulatory mechanisms, such as signaling pathways, protein-protein interactions, DNA damage response, and metabolic pathways. Therefore, the dysregulation in PTMs can lead to a variety of diseases, including diabetes, cardiovascular disease, neurological disorders, and different cancers.
