About This Item

MDL number:
UNSPSC Code:
12352200

particle size

120-200 mesh

pore size

500 Å nominal diameter

Application

Long chain alkylamine controlled pore glass is used in chromatography. Long chain alkylamine controlled pore glass has been used to develop a novel method for the immobilization of nucleotides and for the synthesis of DNA oligonucleotides and their 3′- or (3′,5′)-conjugates.

Other Notes

Ligand is mixture of primary and secondary alkylamines, approx. 1:1.

[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.

The functionalization of long chain alkylamine controlled-pore glass (CPG) with a 3-hydroxypropyl-(2-cyanoethyl)thiophosphoryl linker and its conversion to the support 7 has led to the synthesis of DNA oligonucleotides and their 3'- or (3',5')-conjugates. Indeed, CPG support 7 has been successfully
