Polystyrene is the most common core resin used in solid phase peptide chemistry, due to its chemical stability, compatibility with the majority of organic solvents, and of course cost and availability.

PuroSynth™ supports for Solid Phase Peptide Synthesis (SPPS) are made of polystyrene containing 1% divinylbenzene (DVB) as a crosslinking agent. This polystyrene resin is insoluble in all common solvents, it swells well in most organic solvents and is supplied as uniform spherical beads
