Collection: Polymer Supports for SPPS [Peptide Chemistry]
Polymer Supports for SPPS [Peptide Chemistry] — compiles divinylbenzene cross-linked polystyrene resins functionalized with chloromethyl groups as anchor points in solid-phase peptide synthesis. This group serves as a solid support on which peptide chains are built step by step from the carboxyl end to the amino end.
Chloromethyl polystyrene resins are used as the starting point for preparing Merrifield resin and its derivatives in solid-phase peptide synthesis (SPPS), where protected amino acids are added sequentially before the peptide is released from the resin. Peptide chemists and peptide synthesis laboratories use variations in mesh size and degree of cross-linking to adjust reaction rate and loading capacity.
Product examples in this collection: TCI C1751 55844-94-5 Chloromethyl Polystyrene Resin cross-linked with 2% DVB (100-200mesh) (0.8-1.2mmol/g), TCI C1643 55844-94-5 Chloromethyl Polystyrene Resin cross-linked with 1% DVB (200-400mesh) (1.5-1.8mmol/g), TCI C1750 55844-94-5 Chloromethyl Polystyrene Resin cross-linked with 1% DVB (100-200mesh) (2.0-3.0mmol/g), TCI C1745 55844-94-5 Chloromethyl Polystyrene Resin cross-linked with 2% DVB (200-400mesh) (2.0-2.7mmol/g).
Note the degree of divinylbenzene cross-linking (1% or 2%), which affects resin porosity and swelling in solvents, the particle mesh size, and the loading capacity in mmol/g appropriate to the synthesis scale. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
