Resins for biomolecule separations
Redstone Separations develops new polymeric resins with a rigid structure and with large pores for binding, separation and purification of large biomolecules for use in analytical separation and preparative clean-up.Â
Examples of biomolecules are proteins, enzymes, antibodies and oligonucleotides.
Preview of a new protein separation resin prototype
An example of biomolecule separation using a new type of polymeric resin is shown here. The separation utilizes the hydrophobic properties of the resin. With its new surface hydrophobicity / hydrophilicity it may constitute an alternative to current reversed phase or HIC separation materials. More info upon request – so just contact us, see below.
Scanning Electron Microscopy of the new resin. The resin is characterized with open pores up to ca 0.2 µm. BET pore analysis confirms the macroporosity of the material.
Light microscopic picture of 50 µm particles. The large pores give the beads a rough surface appearance.
Concept material study: chromatographic bioseparation of a set of common peptides and proteins using a pH gradient combined with organic solvent gradient. Taken from Master Thesis, conducted at Lund University (Martina Henning 2026).Â
Method: Particle size ca 50 µm, packed in 10 cm column, id 2.1 mm. Mobile phases., gradient run (blue line): A: 20 mM NaAc, pH 5; B: 20 mM Tris/AcN 7:3 pH 11; Flow: 0.6 ml/min; Analyte conc: 1 mg/ml; Inj. vol: 50 µl.Â
