Abstract:
[reaction: see text] A novel method for the immobilization of nucleotides has been developed. The strategy employs a highly reactive pyrrolidinium phosphoramidate zwitterion intermediate that undergoes nucleophilic attack by long-chain alkylamine-controlled pore glass (LCAA-CPG) to generate an immobilized nucleotide. Quantification of nucleotide loading was accomplished by acidic hydrolysis of the P-N bond and subsequent HPLC analysis of TMP in the presence of an internal standard. Typical nucleotide loadings of 51-59 micromol/g of support were observed.
