The influence of the primary structure (base composition) on the electrophoretic migration properties of single-stranded oligodeoxyribonucleotides in capillary polyacrylamide gel electrophoresis was investigated using homo- and heterooligomers under denaturing and non-denaturing conditions. Homooligodeoxyribonucleotides of equal chain lengths but of different...
