TentaGel® PAP - TentaGel® Resin for the Synthesis of PEG Attached Peptides

Product information

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.
In this special TentaGel® resin the PEG spacer is attached to the polystyrene/DVB matrix by a cleavable linkage. Therefore, the PEGylated compound can easily be cleaved and separated from the insoluble support. This can be achieved with either 10 mL/g of TFA/thioanisole (95:5) for 12 hours at room temperature, or with 10 mL/g of TFA/trimethylsilyl bromide/thioanisole (94:1:5) for 1 hour at room temperature.
