- Gel filtration resins providing exceptional resolution with short run times and good recovery.
- Superdex 30 prep grade is suitable for polishing and formulation of peptides and small proteins.
- BioProcess resin supported for industrial applications.
Superdex prep grade is a preparative gel filtration resin with a composite matrix of dextran and agarose. This matrix combines the excellent gel filtration properties of cross-linked dextran (Sephadex) with the physical and chemical stabilities of highly cross-linked agarose, to produce a separation resin with outstanding selectivity and high resolution. In addition, its low non-specific interaction permits high recovery of biological material. Together these properties make Superdex prep grade the first choice gel filtration resins for all applications from laboratory to process scale.
Superdex prep grade is available in a range of different bulk pack sizes and convenient pre-packed formats for easy scale-up and process development. As a BioProcess medium, Superdex prep grade meets industrial demands with security of supply and comprehensive technical and regulatory support.
