Tosoh Bioscience offers a comprehensive line of process media for isolation or proteins and nucleic acids in research applications and for large scale purification of biotherapeutics. The process media product line consists of TOYOPEARL resins for the capture and intermediate purification steps, and TSKgel resins for the more efficient polishing step. Particle sizes in the TOYOPEARL offering vary from a low of 45 micron to a high of 200 micron, while the average particle sizes of TSKgel resins are 20 and 30 micron respectively. TOYOPEARL resins are available for affinity, ion exchange, hydrophobic interaction, mixed mode and size exclusion chromatography, while high efficiency TSKgel resins are available for anion exchange, cation exchange and hydrophobic interaction chromatography.
Besides their popularity in laboratory-scale product isolation in academic and industrial research laboratories, large columns packed with TOYOPEARL and TSKgel resins can be found anywhere biotherapeutic medicines are manufactured.
