title: A modified procedure for the preparation of di- and triribonucleotides from pancreatic ribonuclease digest of RNA.
abstract: A novel procedure for the separation of oligonucleotides from pancreatic RNase-digest of RNA is described. The method involves a group-separation of uracil-containing and of cytosine-containing nucleotides on Dowex 50W. The obtained groups are further separated on DEAE-Sephadex A-25 by a linear gradient of NH4HCO3.
