TentaGel® MB NH2

TentaGel®resins are grafted copolymers consisting of a low crosslinked polystyrene matrix on which polyethylene glycol (PEG or POE) is grafted via an ethyl ether group which increases stability towards acid treatment and minimizes PEG-leaching. The graft copolymer shows modified physicochemical properties which are highly dominated by the PEG moiety (and no longer by the polystyrene matrix) and has hydrophobic and hydrophilic properties. These copolymers are pressure stable and can be used in batch processes as well as under continuous flow conditions. The PEG spacer is in the range of MW 3000 Da. TentaGel®resins have high diffusion rates and excellent swelling in a wide range of solvents from e.g. toluene to water.TentaGel®Macrobeads are highlighted by extraordinary large particle diameters and high capacities based on the TentaGel®technology and designed for single bead synthesis and single bead analysis.This resin can easily be converted to other supports for solid phase synthesis by acylation with any carboxylic acid containing linker.
