title: Comparison of controlled pore glass and Kieselguhr-polydimethylacrylamide composite as supports for solid-phase synthesis of 23-residue oligodeoxyribonucleotides in milligram amounts.
abstract: Two 23-residue oligodeoxyribonucleotides, corresponding to both strands of a DNA duplex at the OR3 site of bacteriophage lambda, have been synthesized in good yields and in milligram quantities by a solid-phase phosphotriester method using two different supports, Kieselguhr-polydimethylacrylamide composite and controlled pore glass. Rapid purification was possible using high-performance liquid chromatography on radial compression ion-exchange columns. The results and utility of the two supports are compared.
