The 2-D Clean-Up Kit is designed to prepare samples for 2-D electrophoresis that otherwise produce poor 2-D spot-maps due to high conductivity, high levels of interfering substances, or low protein concentration. The reagents quantitatively precipitate proteins while leaving interfering substances, such as detergents, salts, lipids, phenolics, and nucleic acids, in solution.

Ni Sepharose™ excel is an IMAC medium pre-charged with nickel ions very strongly bound to a chelating ligand. Samples that usually cause stripping of metal ions can, therefore, be loaded to the medium. Ni Sepharose™ excel is designed primarily for capture and purification of histidine-tagged proteins secreted into cell culture supernatants from eukaryotic cells such as insect cells or CHO cells.

Epoxy-activated Sepharose™ 6B is a pre-activated medium for immobilisation of various ligands including sugars through coupling of hydroxy, amino or thiol groups on the ligand to Sepharose™ 6B via a 12-atom hydrophilic spacer arm. Medium is formed by reacting Sepharose™ 6B with 1,4-bis (2,3- epoxy-propoxy-) butane. It can be used to couple sugars and other carbohydrates via stable ether linkages to hydroxyl groups.

Fractogel® presents a range of media with 'tentacular' geometries which provide an enhancement of surface topology that give the resins advantageous features for many production processes. The resulting strong binding of biomolecules by a variety of ligands (depending on application and media chosen) and the long lifetime of the material leads to high efficiency and economy of all Fractogel® media. The process media, based on a synthetic methacrylate resin, have high mechanical strength excellent and high chemical stability making the media easy to pack and ‘clean in place'. In addition the base has several advantages over carbohydrate supports as the polymer resin is resistant to microbial degradation and the risk of contamination with endotoxins is greatly reduced.
