General description
Pre-loaded resin for synthesis of peptide acids and protected peptide fragments containing a C-terminal glycine amino-acid residue by Fmoc SPPS.The base NovaSyn® TG is a composite of low cross-linked polystyrene and 3000-4000 M.W. polyethylene glycol. Peptide synthesis is carried out at the ends of the PEG chains that have been functionalized with the hyper-acid labile 4-carboxytrityl alcohol linker. This use of the bulky trityl-type linker helps prevent diketopiperazine formation that can occur during piperidine treatment of Fmoc-protected dipeptidyl resins.,,Treatment of the peptidyl resin with 20% TFE in DCM or 1% TFA in DCM cleaves the product from the resin without affecting the standard TFA-labile side-chain protecting groups. Standard TFA cleavage releases the fully deprotected peptide.
