Abstract:
:Several electrophoretic and chromatographic systems have been investigated and compared for sequence analysis of oligodeoxyribonucleotides. Three systems were found to be useful for the separation of a series of sequential degradation products resulting from a labeled oligonucleotide: (I) 2-D electrophoresisdagger; (II) 2-D PEI-cellulose; and (III) 2-D homochromatography. System (III) proved generally most informative regardless of base composition and sequence. Furthermore, only in this system will the omission of an oligonucleotide in a series of oligonucleotides be self-evident from the two-dimensional map. The sequence of up to fifteen nucleotides can be determined solely by the characteristic mobility shifts of its sequential degradation products distributed on the two-dimensional map. With this method, ten nucleotides from the double-stranded region adjacent to the left-hand 3'-terminus and seven from the right-hand 3'-terminus of bacteriophage lambda DNA have been sequenced. Similarly, nine nucleotides from the double-stranded region adjacent to the left-hand 3'-terminus and five nucleotides from the right-hand terminus of bacteriophage phi80 DNA have also been sequenced. The advantages and disadvantages of each separation system with respect to sequence analysis are discussed.
