What is SEC purity

Size Exclusion Chromatography (SEC) is a chromatographic technique that separates sample molecules based on their size. It is also known as molecular exclusion chromatography or gel filtration chromatography, and is a type of liquid chromatography. SEC purity refers to the analysis of sample protein purity using SEC chromatography. Its principle is that SEC can separate proteins based on their hydrodynamic radius, thereby facilitating protein sample purity analysis.

Proteins in biological systems are usually isolated and extracted in their native physiological state. As a non-denaturing chromatographic method, SEC can achieve protein separation and purification under mild chromatographic conditions with minimal impact on protein conformation and local environment. In addition, SEC technology features high throughput and ease of verification of purified proteins, making it a mainstream technique in protein separation and purification during biopharmaceutical process development.

Biotech company Betapack offersProtein Purity Analysis (Size Exclusion/Reverse Phase Chromatography)analysis services, equipped with both size exclusion and reverse-phase liquid chromatography techniques for protein/peptide purification analysis. These services can be used for the separation and determination of various protein/peptide samples, meeting the purity analysis needs of different protein/peptide samples. You only need to inform us of the experimental objectives and send the samples, and we will handle all subsequent matters, including protein sample processing, chromatographic detection, original chromatographic data processing, and protein purity analysis.
