Helios 30Q is an ion-exchange resin based on highly cross-linked porous polystyrene-divinylbenzene (PS/DVB) monodisperse microspheres, with a chemically bonded, highly stable hydrophilic layer. Helios 30Q has the characteristics of high flow rate, high resolution, high capacity, high rigidity, good biocompatibility, and physical and chemical stability. Compared with traditional chromatography resin, it significantly improves the production efficiency and sample recovery rate of the downstream purification process, and is widely used in the capture, intermediate purification and fine purification of biomolecules such as antibodies, proteins, peptides and nucleic acids.
