Amino acids attached to 2-chlorotrityl resin

Description: 2-Chlorotrityl resins are excellent supports for the preparation of partially protected and fully deprotected peptide fragments by Fmoc batch SPPS. Cleavage can be effected by treatment with AcOH/TFE/DCM (2:2:6), 0.5% TFA in DCM or 30% HFIP in DCM, to yield protected peptide acid fragments without any loss of sensitive side-chain protecting groups. These supports are useful tools for the synthesis of prolyl peptides as the bulk of the trityl handle prevents diketopiperazine formation. 

Loading: 0.4 - 0.6 mmole/g resin.  

Polymer matrix: Copoly(styrene-1% DVB), 100 - 200 mesh.

Storage/Handling: Refrigerator (+4C)

Shipping: Express Courier
