A powerful resin recommended for the synthesis of peptides with acid linkages < 30 amino acids
. Based on ideal swelling properties from incorporating a PEG PS core with a loading of 0.4 - 0.6 mmol/g. This resin features an activated chloride linker, allowing for attachment of the first amino acid in an unactivated form. This resin is recommended for protection of c-terminal cysteine and proline residues due to its steric protection against diketopiperazine formation and 3-(1-Piperidinyl) alanine formation.
