title: Separation of oligonucleotides on ion-exchange derivatives of Spheron.
abstract: Diphenylamine-formic acid hydrolyzate of Bacillus subtilis DNA (a mixture of pyrimidine oligodeoxyribonucleotides) was chromatographed using an ionic strength gradient on seven ion exchangers: five DEAE-Spherons 300 of various capacities, two types of BD-Spheron 300 and DEAE-Sephadex A-25. The suitability of ion-exchange derivatives of Spheron for the chromatography of oligonucleotides is discussed. The separation of mono- to undeca-deoxyribonucleotides was achieved.
