    Protein Post-Translational Modification Analysis Service

      Post-translational modifications (PTMs) of proteins are critical chemical modifications occurring after protein biosynthesis, crucial for regulating various cellular processes such as signal transduction, gene expression, and protein-protein interactions. PTMs, which include phosphorylation, acetylation, ubiquitination, and glycosylation, modify the structural, functional, and locational attributes of proteins by appending biochemical groups to specific amino acid residues. Accurately identifying and localizing PTMs are paramount for deciphering cellular biology's complexities and their implications in diagnosing and treating diseases.


      MtoZ Biolabs employs mass spectrometry (MS) to analyze protein PTMs, utilizing its high sensitivity and precision, which are essential in proteomic research. MS is capable of detecting and quantifying trace modifications within protein samples, offering extensive details on modification types and sites, thus facilitating comprehensive PTM analysis.


      Analysis Workflow

      1. Sample Preparation and Pre-treatment

      We handle a diverse array of samples, including tissue, blood, urine, and other biological specimens, preparing them for analysis.


      2. Protein Digestion

      Specific enzymes are used to digest proteins into peptides, making them amenable to subsequent analyses.


      3. MS Analysis

      Through liquid chromatography-tandem mass spectrometry (LC-MS/MS), we precisely identify and quantify various PTMs.


      4. Data Analysis and Reporting

      Advanced bioinformatics approaches are applied to parse data, culminating in detailed assessments of modification types and locales.


      Sample Submission Requirements

      Types: We process various biological samples, encompassing tissues, blood, cell cultures, and bodily fluids.


      Quantity: A minimum of 10 μg of protein is necessary to ensure a thorough analysis.


      Storage Conditions: To preserve the integrity of proteins and their modifications, samples should be kept frozen and protected from repeated freeze-thaw cycles before analysis.
