    Molecular Weight Determination Service

      Molecular weight is a critical measure of biomolecule size, including proteins, peptides, and nucleic acids, in biopharmaceuticals. It significantly influences drug efficacy, stability, biological activity, and safety. Evaluating the molecular weight provides insights into a biopharmaceutical's structural complexity, purity, and post-translational modifications, essential for assessing drug quality, efficacy, and safety. Variations in molecular weight can affect drug performance and may be linked to adverse reactions. Predominant techniques for molecular weight determination are MALDI-TOF and ESI-MS. MALDI-TOF offers a rapid assessment suitable for biomolecules, while ESI-MS provides high sensitivity for complex samples.

      Analysis Workflow

      1. Sample Preparation: Treating the biological sample to ensure compatibility with mass spectrometric analysis.

      2. Ionization: Employing electrospray ionization (ESI) or matrix-assisted laser desorption/ionization (MALDI) to ionize the sample molecules.

      3. Mass Analysis: Determining the ions' mass-to-charge ratio (m/z) using time-of-flight (TOF-MS) or quadrupole mass spectrometers (Q-MS).

      4. Data Analysis: Employing specialized software to process and interpret the data, yielding precise molecular weight measurements.
