半岛bd体育手机客户端 说明
应用
- Acid labile resin used in Fmoc-based solid phase peptide synthesis.
- Mild acidic cleavage conditions lead to the release of the peptide acid where fully protected peptides can be released if desired.
- 2-Chlorotrityl chloride resins prevent racemization of the first amino acid and are thus very useful when racemic mixtures are forming (common with residues such as His or Cys).
- This resin also prevents diketopiperazide formation, which can be an issue with proline C-terminal peptide sequences.
Use:
- Attachment of the first amino acid residue is effected by stirring the resin, the protected amino acid, and excess diisopropylethylamine (DIEA) in dichloromethane.
- Cleavage of the final protected peptide fragment is achieved under very mild conditions using either acetic acid/trifluoroethanol (TFE)/dichloromethane (1:1:8; v/v/v), hexafluoroisopropanol (HFIP)/dichloromethane (1:4; v/v) or simply 0.5% trifluoroacetic acid/dichloromethane (v/v).
- Higher concentrations of TFA can be used if retention of peptide side chaing protecting groups is unimportant. Note that trityl chloride is moisture-sensitive, and, therefore, should be stored and handled appropriately.
- If the resin becomes deactivated, treatment with acetyl chloride or SOCl2in toluene before use is recommended to restore its activity.
