Resins for Solid Phase Peptide Synthesis

Amino Acid 2-Cl-Trt Resins

Fmoc-Amino Acid 2-Cl-Trt Resins

Fmoc-Amino Acid-Wang Resins

Multiple Antigen Peptide (MAP) Resins

Rink Amide Resins

Unsubstituted Resins

For peptide synthesis, researchers prefer to use small particle-sized resins with low cross-linkage. Such resins allow rapid diffusion of reagents inside the beads, and their swelling properties allow them to better accommodate large portions of the growing peptide chain.

Polystyrene is the most common core resin used in solid-phase peptide synthesis, but other core matrices include polyacrylates, polyacrylamides, and polyethylene glycols.

How to Choose A Resin for Peptide Synthesis?

If the customer wants to synthesize a very large peptide (30 to 50 amino acids), then a resin with low substitution (0.1 to 0.4 mmol/g) is best. For peptides of 10 to 20 amino acids, standard substitution resins (0.5 to 1.2 mmol/g) can usually be used.
