Glen Research 5’-CE (ß-cyanoethyl) Phosphoramidites are designed for the production of 5’-5’ or 3’-3’ linkages, useful in antisense studies, or to synthesize oligonucleotide segments in the opposite sense from normal synthesis, for structural studies. These monomers are packaged in ABI-style vials unless otherwise requested..
5’-supports are used to produce oligonucleotides with nuclease resistant 3’-3’ linkages at the 3’ terminus (by attaching regular 3’-CE phosphoramidites) or to produce oligonucleotide sections in the opposite sense (by attaching 5’-CE phosphoramidites). ABI-style columns are supplied unless otherwise requested.
