Description
Methyl Phosphonamidites may be used in DNA synthesizers following conventional CE Phosphoramidite protocols to produce oligonucleotides containing one or more methyl phosphonate linkages.However, deprotection and purification techniques differ and a description of the procedures is included in the Technical Bulletin.We also offer the dC monomer with acetyl base protection.1This protecting group is removed with ammonium hydroxide during the cleavage step, eliminating modification at the dC sites during the deprotection step using ethylenediamine in ethanol.

Usage
- Coupling: 6 minutes. Note to prevent degradation of the methyl phosphonate linkage, low-water content oxidizer (40-4032) and DMAP for Cap B (40-4020) are recommended.
- Deprotection: See Technical Bulletin for details (http://www.glenresearch.com/Technical/TB_Me-Phosphonamidites.pdf).
