title: [Stepwise synthesis of oligonucleotides. XXXIV. Preparative synthesis of trinucleoside diphosphates and longer oligoribonucleotides using immobilized ribonucleases].
abstract: Immobilized guanyl-specific ribonucleases from Aspergillus clavatus (C2), A. oryzae (T1), and Bacillus intermedius 7P (Bi) have been used for preparative synthesis of ten trinucleoside diphosphates, three tetra- and one pentanucleotide having the only guanylic acid residue at the 5'-end. The nucleotide sequence of the oligonucleotide synthesised determined the choice of the ribonuclease.
