Novel photocleavable universal support for oligonucleotide synthesis.
Anderson E., Brown T., Picken D.
A novel photocleavable universal support for the automated solid phase synthesis of oligonucleotides is described. The linker between the growing oligonucleotide chain and CPG support contains a nucleophilic amine protected with a photocleavable group. On exposure to UV light, this group is detached and the free amine affords cleavage of the oligonucleotide from the support. The use of long wavelength UV light avoids damage to the DNA.
