Abstract:
:Retro-ACP (74-65) fragment was synthesized on a novel 4% tri-(propylene glycol) glycerolate diacrylate cross-linked polystyrene (PS-TRPGGDA) support. The peptide is grown from the functional site present in the cross-linker, which makes it unique and cost-effective among other styrene based polymer supports. A comparative study with Merrifield resin indicates high yield and purity of the peptide synthesized on the novel support.
