MagReSyn® SAX

For rapid protein fractionation of proteins by ion exchange & concentration and clean-up of proteins from dilute solutions pre-MS analysis

MagReSyn® SAX (strong anion exchange) is a magnetic polymeric microparticle support designed for capture, purification and recovery of biomolecules such as proteins/peptides, enzymes, antibodies by exploiting differences in net charge to reversibly adsorb oppositely-charged molecules.

MagReSyn® SAX is ideal for fractionation of complex biological mixtures (e.g. serum, plasma, urine, CSF, cell lysates, culture supernatants etc.) prior to analytical methods such as 2-dimensional electrophoresis, HPLC or Mass Spectrometry. The microparticles have an exceptional capacity allowing for experimental miniaturization and elution in minimal volume.

Support: Proprietary polymer microparticles containing iron oxide (magnetite)
Binding capacity: > 20 (BSA) per ml
Bead size: ~5-10 µm
Formulation: 20 suspension in 20% ethanol
