    Protein Full Spectrum Analysis Service

      Proteins, the direct executors of biological functions, shape life's diversity through their complex and varied forms. To advance our understanding of these biological building blocks, MtoZ Biolabs offers comprehensive proteomic analysis using cutting-edge mass spectrometry. This method enables the detailed identification and analysis of proteins and their modifications in biological samples like serum, urine, and cell lysates, ensuring a thorough understanding of their types, quantities, and post-translational modifications.


      MtoZ Biolabs excels in delivering top-tier full-spectrum protein analysis services, aiding researchers in deciphering biological complexities. At its heart, the lab employs a combination of shotgun proteomics, high-performance liquid chromatography (HPLC), and mass spectrometry (MS) to identify and quantify proteins in intricate biological samples accurately.


      Analysis Workflow

      1. Sample Preparation

      Biological samples are preprocessed and purified to prepare for analysis.


      2. Protein Digestion

      Proteins are enzymatically digested into manageable peptides.


      3. Peptide Separation

      Using HPLC, peptides are separated based on their physicochemical properties.


      4. Mass Spectrometry Detection

      Peptides undergo mass measurement and sequence analysis in a mass spectrometer, which provides detailed information about their mass-to-charge ratios and fragment ions.


      5. Data Analysis

      Advanced bioinformatics tools and databases are utilized to interpret mass spectrometry data, identifying protein types, quantities, and modifications.


      6. Report Writing

      A comprehensive report is produced, detailing protein identities, modification sites, quantities, and analytical interpretations.
