Abstract
The (33-42) fragment of Alzheimer's 13-amyloid peptide (Gly-Leu-Met-Val-Gly-Gly-Val-Val-Ile Ala) [1] was synthesised on a 2% 1,4-butanediol dimethacrylate cross-linked polystyrene (PS-BDODMA) support. The new polymer support was prepared by aqueous free-radical suspension polymerisation of styrene and 1,4-butanediol dimethacrylate. The peptide was synthesised.using Boe-amino acids and cleaved· from the resin by trifluoroacetic acid (TFA) in high purity and yield. The crude peptide was purified by HPLC and characterized by amino acid analysis and MALDI TOF MS.
