HPLC protein purity analysis service offers a robust and scientifically validated approach to quantifying protein sample integrity across research and manufacturing environments. Based on High-Performance Liquid Chromatography (HPLC), this service translates advanced chromatographic principles into practical, high-resolution analysis of protein purity, isoform distribution, post-translational modifications, and aggregation states.
Since its inception in the 1960s by Csaba Horváth at Yale University, HPLC technology has undergone continuous evolution—transitioning from classical liquid chromatography to high-pressure systems with enhanced detector sensitivity and column selectivity. These advancements have culminated in powerful workflows that now support routine applications in protein therapeutics development, structural biology, and clinical-grade quality control.
To address the growing demand for traceable, reproducible protein analysis, MtoZ Biolabs has developed a dedicated HPLC-based protein purity analysis. Leveraging high-sensitivity HPLC instrumentation, automated injection systems, and expert-driven data interpretation, we empower both life science researchers and biopharmaceutical manufacturers with the reliable data they need to validate protein quality, ensure process consistency, and meet global regulatory standards.

Workflow of HPLC Protein Purity Analysis Service
1. Selecting the Appropriate HPLC Column
(1) Evaluate protein characteristics (e.g., molecular weight, hydrophobicity, charge, structural conformation) to select the appropriate chromatographic mode—RP-HPLC, IEX-HPLC, or SEC-HPLC;
(2) Incorporate guard columns where applicable to protect the analytical column, improve column life, and enhance throughput in high-sample-volume scenarios.
2. Sample Preparation
(1) Adjust sample parameters such as pH, ionic strength, and concentration to match HPLC conditions and prevent protein degradation or aggregation;
(2) Apply filtration (e.g., 0.22 μm) or centrifugation to remove particulates; protease inhibitors and low-temperature handling are used to preserve protein integrity.
3. Setting HPLC Conditions
(1) Configure mobile phase composition, flow rate, and gradient program based on protein physicochemical properties and selected column type;
(2) Select appropriate detection wavelengths (typically 214, 220, or 280 nm) to ensure optimal signal response for target analytes.
4. Sample Injection and Analysis
(1) Utilize precision-controlled auto-injectors to ensure consistent sample volume and minimize manual variation;
(2) Conduct real-time system monitoring of pressure, baseline, and peak response to maintain analytical consistency and reproducibility.
5. Result Interpretation
(1) Analyze chromatographic profiles to assess number, shape, and area of peaks, enabling qualitative and semi-quantitative evaluation of purity and impurities;
(2) Annotate chromatograms with identified peaks representing monomers, aggregates, or isoforms for clear client interpretation.
6. Quantitative Calculation
(1) Perform purity quantification based on integrated peak area or height, normalized to internal standards or reference runs;
(2) Conduct replicate injections and statistical analysis (e.g., %RSD, confidence intervals) to ensure data robustness and reproducibility.
Sample Submission Suggestions
To facilitate accurate and reproducible results from our HPLC protein purity analysis service, MtoZ Biolabs provides the following sample submission recommendations:
1. Sample Types and Quantities
(1) Cell Extracts: 100–1000 μg protein
