Postnova Analytics has published an application report that describes a promising new protein purification technique based on diffusion. Protein purification is a widely used and important tool for biotechnology labs. Traditionally the most commonly used techniques for protein purification have been based upon column chromatography, ultracentrifugation and ultrafiltration.

Postnova Analytics reports on an informative new book that introduces scientists to Thermal Field-Flow Fractionation and discusses its advantages over the fundamental problems associated with traditional column-based analytical techniques commonly used to characterize polymers and macromolecules.

The PN3621 Multi-Angle Light Scattering (MALS) detector from Postnova Analytics combines outstanding performance, high precision and reliability design features to facilitate advanced characterization of proteins, conjugates, macromolecules, and nanoparticles. The PN3621 is commonly used in conjunction with Gel Permeation Chromatography (GPC-MALS), Size Exclusion Chromatography (SEC-MALS) or Field-Flow Fractionation (FFF-MALS) to determine distributions of mass, size and composition independent of column calibration by reference standards.
