HPLC Protein Purity Analysis Service

    Protein purity refers to the relative proportion of the target protein in a protein sample, typically expressed as percentage. The higher the purity, the higher the proportion of the target protein in the sample. Measuring protein purity is an important aspect of biochemistry, molecular biology, and biotechnology. By determining protein purity, the quality of the extracted protein sample can be assessed, which can provide a reference for subsequent experimental procedures. High purity protein samples help ensure the reliability of experiments, especially when studying the functions, structures, and interactions of proteins. In the biopharmaceutical industry, protein purity is a critical parameter that can optimize production processes and improve product quality.


    High-performance liquid chromatography (HPLC) is a chromatographic method used for separating, quantifying, and identifying components in complex mixtures. Since its development in the 1960s, HPLC has become the main method for determining protein purity. The principle of HPLC determination of protein purity is based on the retention time (RT) of proteins on the chromatographic column, such as reversed-phase HPLC (RP-HPLC), ion-exchange HPLC (IEX-HPLC), or size-exclusion HPLC (SEC-HPLC). HPLC uses the separation effect on the column and a highly sensitive detector to quickly and accurately measure protein purity.
