    Biopharmaceutical N-Terminal Sequencing Service

      N-terminal sequencing identifies the amino acid sequence initiating from the N-terminal of proteins, crucial for confirming protein identity, understanding functional mechanisms, and evaluating therapeutic and safety impacts of post-translational modifications. The N-terminal sequence can influence protein stability, activity, and biomolecular interactions, essential for consistent therapeutic protein production and compliance with strict regulatory standards.

      Services at MtoZ Biolabs

      In biopharmaceuticals, N-terminal sequencing is pivotal. At MtoZ Biolabs, we employ the Edman degradation method, known for its precision in sequentially identifying amino acids by removing one residue at a time from the N-terminal. We also enhance our sequencing with advanced mass spectrometry, especially valuable for proteins with complex structures or high molecular weights.


      Analysis Workflow

      1. Sample Preparation: Protein purification and preparation under stringent conditions to maintain integrity and prevent degradation.

      2. Edman Degradation Sequencing: Cyclic chemical reactions on the protein's N-terminal to cleave and identify each amino acid.

      3. Mass Spectrometry Analysis: Secondary sequence confirmation when needed.

      4. Data Analysis and Reporting: Expert interpretation of data with comprehensive reports on sequence accuracy, modifications, and anomalies.
