HPLC Protein Analysis Service

    High performance liquid chromatography (HPLC) is a technique that utilizes chemical and physical interactions between the stationary phase (particles inside the chromatographic column) and the mobile phase (solvent) to achieve high-resolution and high-sensitivity qualitative and quantitative analysis of proteins. It holds great potential in various fields such as bioscience, drug development, and quality control. As the field of HPLC protein analysis progresses from the early experimental stage to modern diversified techniques, HPLC not only supports protein research but also helps elucidate the complexity of biological systems, identify new drug targets, and optimize biopharmaceutical production processes.

     

    The primary modes of HPLC protein analysis include reversed-phase high-performance liquid chromatography (RP-HPLC), ion-exchange chromatography (IEX), size-exclusion chromatography (SEC), and affinity chromatography (AC). RP-HPLC separates proteins based on hydrophobic interactions, suitable for protein purity identification and peptide analysis. IEX separates proteins based on charge differences, enabling the determination of protein isoelectric points and charge distribution. SEC separates proteins based on molecular size, evaluating molecular weight, polymer, and subunit composition. AC achieves protein separation through specific biomolecular recognition and is commonly used to study protein-ligand interactions

     

    Analysis Workflow

    1. Sample Preparation

    Necessary pre-treatments such as impurity removal, concentration, and desalination are performed on received samples to enhance the accuracy and repeatability of analysis.

     

    2. HPLC Method Optimization

    Based on protein characteristics and client requirements, appropriate chromatographic columns, mobile phases, and detector parameters are selected. Conditions such as flow rate, mobile phase composition, and temperature are set accordingly.

     

    3. HPLC Analysis

    Samples are analyzed using the optimized HPLC method, and chromatograms are recorded and analyzed to obtain information on protein separation, purity, concentration, etc.

     

    4. Data Processing and Analysis

    Dedicated software is used for peak identification, quantification, and identification of chromatographic data.
