| Abstract: | Modifications of the chemical method of DNA sequence analysis that permit rapid and reliable sequence determination of single-stranded oligodeoxyribonucleotides as short as 4 nucleotides in length are reported. The principal changes made were increasing the level of chemical modification and optimizing the conditions for recovery of the chemically modified oligodeoxyribonucleotides. This method includes two approaches to the removal of [γ-32P]ATP from 32P-labeled oligodeoxyribonucleotides and is especially useful in the determination of the sequence of chemically synthesized oligodeoxyribonucleotides, which are generally between 4 and 20 nucleotides in length. |
