The following 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.
